Tonight's Saturday Night Gun Pron is a quick progress report on my M4P(piston) project. The parts are starting to roll in, with these being the biggest items, so far.

The piece of rail on the right is a new widget from GG&G. It lets you install the rail on a GI handguard without going through the agony of removing the handguard first. Three toggles lock the rail into place with a screwdriver.

The most significant item is the PWS one-piece extruded buffer tube. It does away with the castle nut and instead uses three hex setscrews to apply pressure to the endplate, and lock up the buffer tube tight against the lower receiver. As an added advantage, it has an extended "lip" to prevent the bolt carrier from tilting, something that is supposed to be a common occurrence with piston guns.

Now that I think about it, that may make some sense. Despite the scorn heaped on the M16 gas-impingement system, the hot gas is piped directly into the bolt carrier, with all mechanical forces acting on the centerline of the bore. A piston weapon has a piston, rod, rings, and springs above the bore centerline. If everything is built right, the mechanism is perfectly parallel with the bore, but there is still an unbalanced force pushing back from above, thus making the rear of the carrier tend to "dive". Maybe Gene Stoner had some good ideas, including cutting back on the mass of moving parts.

This is as far as I've gotten. I'm still waiting for the upper receiver, which is the whole reason for the project in the first place. With luck, it will be here some time this week.

Despite my searching, I couldn't find every last pin and spring, so I bought $21 worth of parts from Brownells. Meanwhile, I'll be tuning the trigger parts, and scoping out a new scope. I also ordered another PWS buffer tube. I'll put it on one of my current M4s, which have known accuracy, and see if this new type of tube can increase accuracy. I was impressed with the solid feel of everything as I put it together, so it's worth my while to test this tube on another rifle.

Overall, this buffer tube looks like one of those ideas that should have been adopted 40 years ago. It's easier to install, seems more solid, and has other neat features. It is, however, considerably more expensive than the dirt-cheap generic parts out there. I hope it's worth the extra cost. Only testing will tell.

Tonight's Saturday Night Gun Pron brings us to the basic completion of the M4P(piston) project. There are still "I"s to dot, and "T"s to cross, but it's almost ready for its first test fire.

The Adams Arms gas piston upper arrived a couple of days ago, so the first thing I did was to take it apart to see what made it tick.

Compared to the previous project, the M4E2(economy), it has a mid-length handguard which covers the operating rod, but otherwise the same 16.1 inch barrel. At first I thought it was a medium-heavy barrel, but when I took the handguards off, I found the only real (and minor) disappointment of the whole project.

The bolt head is identical to the original AR15 concept, except there are no gas vent holes, no piston rings used, and a slight spring on the tail of the bolt to keep everything in a forward position. The bolt carrier has several differences, including redesigned glide pads, and a noticeable rounding of the bottom rear, to assist in getting the upper receiver closed despite the spring pressure that tends to push the entire assembly to the rear. This may also be the source of the "bolt tilt" mentioned by some sources.

After spending most of today getting the trigger pull down from 20 pounds to 11, it finally dawned on me that one of the trigger components might be the culprit. I put in another hammer and spring, and the trigger pull immediately dropped to a bit over seven pounds, with plenty of potential for Nanolube to continue to work its magic. I looked at the old hammer, and it seemed a much cruder forging than the new one. I had just grabbed parts from my stash, but that old one went into the trash. Trigger work can now continue as normal.

Here's the rifle so far. I'm still waiting on a titanium firing pin, rear iron sight, scope, and other minor items like sling and swivels. But at least I have enough to begin testing.

The handguards are not identical between top and bottom, and seem a bit flimsy. I can probably adapt a Midwest Industries cantilever-type quad rail handguard, but I'm not ready to make that investment, yet. The other piece of New Technology is the GG&G "install from the outside" rail on the bottom half.

I wasn't ready to take them at their word, so I removed the handguards just to see how the mechanism works. It's vey ingenious, but due to the variations in quality and design of handguards, you might achieve better results by removing it. Here's what things look like from the inside.

No heat shield in the top half, but there's no hot gas tube up there, either. The heat shield in the bottom is a bit flimsy, and the rail's toggle clamps scrunched things up a bit and pulled the heat shield out of its slots when everything was tightened enough. Your mileage may vary due to the type of handguard you have.

Overall, I'm impressed with the concept, and have a second piece of rail I'll try on the "glacier guard" handguards on the M4E2.

That's the project status as of now. If I don't find the time to fire it this week, next week for sure. I want to compare it to the accuracy of the M4E2, and then I'll put a PWS buffer tube on it, and test it again. That way I'll be able to tell if the increased rigidity adds anything to accuracy. In one sense, I hope it doesn't make much difference, one way or another. Otherwise, if it provides a significant improvement, I'll have to replace the buffer tube on all my AR15s.

Good Morning Win-Mag - as always an exemplary ‘gun-pron TM’ session. Trigger pull of 20 lbs - yikes. Glad you were able to reduce it into the acceptable range. Looking forward to the upcoming range session report. We bet your parts bin is exceeded only by Brownells.

My range time now is mostly indoors. Shooting the Ruger .22 at 20 yards is good practice for the upcoming spring shooting session at the old outside range. Keeping them in the black on the shoot-n-see targets, simply cannot see the hits at 25 yards but I can at 20 so that’s where the target hangs. Not there yet but as the old quip goes, practice and then practice some more. Goal is to get acceptable scores on the 50 yard targets in the spring. Hope springs eternal.

I think I spent more time going through my parts than actually assembling the rifle. One bonus was I found about a dozen of those tiny horseshoe clips that are used to keep the ejection port cover hinge on the upper. I lost five or six before I got the last engraved cover back on. Now I can try to think of something cute to put on the inside of this cover.

11 lbs to 7 lbs on the trigger because of springs and “parts”?! That’s a big improvement! Do you think the springs were too stiff, or were match-up surfaces excessive?

Heh, yep, it’s rare I don’t find something else each time I look for a specific item. Today it was the old set of drill bits which I had to replace since I ‘lost’ the old ones. Sigh. One of these days I’ll get organized. :-)

Kudos on finding the horseshoe clips.

It was the hammer's fault. I have some Wolff extra-power hammer springs, but they add only about two pounds of trigger pull, and I don't use them anyway. Not only did the second hammer provide immediate relief, but I could see the hammer and trigger start to "print" against each other almost immediately. With the old hammer, I was seeing a strange wear pattern that said some part of it was grinding against the trigger and sear that shouldn't.

I had that same thought when I was pawing through my AR15 parts for the umpteenth time, but I took a nap and the urge went away. :)

Seriesly, I figured out that if I totally organized all my parts, I would never build another M-faux again, which I found depressing. So I compromised, and developed a compromise system of organization. As I grabbed a part, I'd toss it into one of three boxes, marked "small, medium, and large".

Question for you...

My daughter and I have "national match" triggers in Armalite AR-15s that we own. The triggers are national match, but the springs aren't. They're not bad triggers as far as AR-15 triggers go. Hers is an SPR-1 upper on top of an Eagle-Armalite lower. Mine is an M4gery. These triggers break at "about" (guessing here) 5 lbs, but they're definitely two stage.

I was told that IF I swapped the springs, that the triggers would become "true" national match triggers. Meaning (I suppose) that it takes less force to break the sear from the hammer and free it at trigger pull.

So exactly what sort of springs should I replace for these triggers? Thanks in advance for any advice. :-)

I was told that IF I swapped the springs, that the triggers would become "true" national match triggers.

Without seeing the actual trigger parts, I can only guess, but one thing for certain is that "National Match" has nothing to do with any springs, especially single vs two-stage trigger pull.

Some target triggers are made from modified GI parts. The hammer spring is lightened, and much of the hammer is cut away to remove mass. But there still has to be enough energy in the hammer spring to reliably fire any kind of primer. A slightly lighter trigger spring can be used, too.

The trigger, which operates on the see-saw principle, has setscrews in the front and rear. The front setscrew determines how much overtravel the trigger will experience once the sear has released the hammer. The rear setscrew determines how much take-up the trigger will have before it engages the hammer notch.

These types of triggers can be adjusted, and mis-adjusted by the user. I had one, and after reading all the warnings about possible dire consequences, opted not to use them. Instead, I went with the newer unitized drop-in triggers. They operate on the same principle, but with optimized parts geometry, and everything is sealed to prevent tinkering. NRA safety rules allow a minimum of three pound trigger pulls. For a rifle that may also be used in zombie defense, I find that five-pound no creep, no takeup, no overtravel triggers work just fine. Five pounds feels like nothing if everything else is tuned properly.

My last two builds involved getting GI trigger parts to work better. Everything is factory stock, but working in the contact surfaces with Nanolube has produced (from the one that is now fully broken-in) three pounds of smooth takeup of the first stage, and another two pounds of crisp, clean-breaking pressure to actually fire the weapon. I specifically explain that to anyone who fires them, especially if they are used to GI M16-type trigger pulls. These triggers are not unsafe, but you have to know what to expect, otherwise that first round can get away from you.

Bottom line: single vs double stage depends on parts geometry, or setscrews, not "special springs". I do not trust my adjustments to remain fixed over lots of firing, so I've gone to commercial unitized triggers for all my single-stage trigger work. And careful tuning can turn GI parts into vey nice, crisp double-stage triggers, with a little work, a little care, and a lot of knowledge. My goal is always safety first, then reliability, and finally a "nice" trigger pull.

I hope that helps. Thanks for asking.

Iffin you don't mind, I'll take the trigger out again... take some photos, and post them. It "sounds" like somebody gave me bad info with the line about only needing to swap springs.

I like the results you obtained with Nanolube though. I think I'll go that route... eventually. :-)

Thanks buddy! :-)

I won't bore you with photos. :-) Besides, I'm sure you'll understand what I'm saying, and probably smile to yourself and say, "Duh-Huh!"

Anyway... I just put the trigger back IN my rifle and while it was out I verified that it is indeed an Armalite national match trigger. It has four positions on the disconnector where the spring can be repositioned, thus reducing or increasing trigger pull by a few ounces between positions.

Anyway... after finally understanding HOW this trigger works, I realized something. The mating surfaces of the trigger and disconnector were NOT even close to being uniform. Both had a low spot. I spent about an hour c-a-r-e-f-u-l-l-y removing these low spots with 600 grit worn wet/dry sandpaper. Then I snapped it all back together. Me and one of my buddies here agreed that it probably took two pounds of pull from the trigger.

It's still an AR-15 trigger... feels like one, operates like one, looks like one! But it's just a little lighter now. Not much, but a little. :-)

Ooooh, a trick disconnector? I never heard of that, but it can make sense. But you hit on the key thing, the mating surfaces. Ideally, they should be smooth as glass, and shine like chrome. There is no earthly way to achieve that other than by painstaking hand labor.

I put the first 90 rounds through the new M4P yesterday, after applying the Nanolube treatment. The all-stock trigger system presently has a trigger pull a bit under seven pounds, with a good, but not perfect, takeup. I'll continue the Nanolube treatment, and check again after another hundred rounds, or three magazines. I expect the pull will lighten up another pound, and the takeup will be almost perfect.

One slight "problem" is that this particular rifle looks like it has all the makings of another rifle that can shoot far better than I can. I might spend on one of those unitized target triggers for it, anyway. Even there, I still apply tiny drops of Nanolube to the mating parts, because as fine as they are, it still can be approved.

Two of my M-faux are so well-tuned that there is no roughness in trigger pull or overall functioning that I can "zone out", and the world shrinks down to the image in the scope, and a bit of pressure against the pad of my index finger. I tell myself I like the sight picture, feel a bit of recoil, and notice that a new hole appeared in the target. I can only do that with two rifles, so far. But this is what can be done when all the right components, including gunsmithing skills, come together.

Here's the results of the first magazine put through the M4P(piston).

Except for a permanent scope, and sling swivels, the configuration is basically complete. The backup sights are new Midwest Industries extra-low profile models. The scope was not zeroed from an earlier session on another rifle, but still managed to shoot this first group:

The five circled shots we fired at ten yards, just to make sure I was hitting the paper. The other 25 were fired at 50 yards, the limit of the indoor range. No matter how careful I am, I still manage to throw in a few fliers. A bit more gunsmithing on my part, and a lot more effort with my marksmanship, and it looks like this rifle can keep ordinary M193 ball in the X-ring all day long.

Now, for a bit of rifle heresy. A gas-piston AR15-type is a feelthy weapon. Burnt powder was blown from the piston halfway back to the receiver, covering the barrel, piston rod, and handguards, inside and outside. True, it was easy to clean up, but there were a whole lot more square inches of fouling compared to the gas-tube system of the "traditional" AR15. There, the fouling is limited to the gas tube, and the bolt and carrier. It's more baked-on, but a much smaller area.

I can't detect any difference in handling, and accuracy can be astounding in either type of rifle. I'd give a slight edge to the gas-tube model just due to the smaller number of moving parts.

More testing will be coming shortly, along with testing another one of my "pet" M4s with a new PWS extruded buffer tube, to see if it enhances the accuracy of an already known accurate rifle.

Yep! The mating surfaces of the disconnector and hammer BOTH had low spots. I could tell right off when I shined a light on them because the bright spots revealed where contact was occurring. The disconnector had "about" a .003 low spot and the hammer was less. The hammer took no time to clean up with the 600 grit wet/dry sandpaper. But the disconnector took over an hour. That disconnector was a real pain in the neck. The spring which holds tension against the trigger was very much in the way, and I had to take it off. It would have been easier had I removed the disconnector from the trigger, but I simply wasn't in the mood to be knocking out small pins. All in all, I'm pleased. I'm going to try to find some Nanolube this weekend.

Anyway... thanks... because if not for you, I never would have given this a second thought! :-)

So much for all the talk of piston systems making the AR platform cleaner. :-)

I've often wondered exactly WHERE a piston driven AR exhausts. The FAL has two small vents on the tube, a few inches behind the port, and then that little regulator just AT the port. The SKS has two small vents on the tube similar to the FAL, but no regulator.

It sounds like the piston driven AR simply exhausts inside the front grips, and as best I can tell, there's not a full length gas tube... right? :-)

Thanks buddy! :-)

Sounds like a reason to stick with the gas pipe.

Is there an overriding counter-reason in favor of the piston?

Correct. For any gas-operated weapon, the powder fouling has to go somewhere. In the case of this AA upper, it's spread out thinly all over. My Sig 556 keeps most of it on the piston and housing. It gets pretty filthy, too, and takes a lot to clean it. Some people have claimed firing 5000 rounds through the Sig without cleaning. That may be true, but I consider that abuse of a weapon, even for an AK47.

As far as my limited experience so far with a gas-piston goes, I can't see any one major benefit from one type to the other, except personal preference.

I suppose a piston driven weapon is better than using the bolt as part of the PATH for exhaust...as in the case of DIGS with the AR. But I don't know. Perhaps time will tell. :-)

Went to the gun show today...and was sore tempted by a “complete AR-14 lower” for $150.

I didn’t do it, but I don’t know how long I can hold out....

Went to the gun show today...and was sore tempted by a “complete AR-14 lower” for $150.

Considering a lot of mid-grade stripped lowers cost $150, that deal sounds almost too good to be true. Caveat emptor

And with those words of wisdom, it's time to ignore all that, and check out tonight's Saturday Night Gun Pron

There I was, minding my own business, driving to some place unimportant, when the cell phone rings. It's my friend, calling me with a hot tip. He said our favorite EBR emporium just got in the first samples of an item he first saw at the 2011 SHOT show in February.

Knowing what it took to get my Kimber Solo when it first came out (persistence, and an ill-informed store clerk), I immediately headed to the store.

Once there, I laid out my debit card (handily, just refilled), and bought this on the spot.

The new Ruger Mark III 22/45 with rails and threaded barrel. This will be the vehicle for my first suppressor, I hope. In the meanwhile, I put on a leftover Docter sight, and I'm heading back to the range tomorrow.

Also, being the geek that I am, I've already ordered a special low-profile Docter mount for the Ruger, which should allow me to remove both rails. The gun can also be bought with regular sights, but most cans are too tall to allow the sights to work, so something higher is needed.

And, from long and painful familiarity with the Ruger .22, I'm getting a combined trigger/takedown/disconnect-remover kit. And some fancier grips than these optional rosewood ones. My primary task tomorrow is to see how it likes various brands of subsonic ammunition.

The other thing I learned in the phone call was some good Class III news may be happening after the first of the years. The old "approval of local chief law enforcement officer" provision in the 1934 NFA may be declared superfluous and replaced with the same NICS check that all FFL sellers have to perform. In 1934, local cops and feds had to run all sorts of investigations to see if you were a good guy. That's why, even if you already have the local approval, it takes six months for the feds to process things.

The NICS check, despite being scorned by liberals, provides a more thorough check in seconds that what all the federal paperwork does in six months. While politically the government might like the "go slow" approach, it still takes real time and money to do something that's already doing a better, faster job, and is already paid for.

I guess they figure they can save our tax money by dropping the manual background check, and use it towards buying more weapons for Mexican drug dealers.

Still, I'm grateful for small favors. I was also instructed to wait until after the 2012 SHOT shot so my buddy can see if he can make some deals out there, because he's trying to get his Class III license back, and he has lots of industry connections. I wonder how much I'd have to pay him so I could work behind his counter? :)

holy crap! Mister mag... That’s exactly the same Ruger I got for my (patiently awaited) suppressor. The Mark III 22/45. The optics are similar, though mine is a Trijicon red-dot sight. Same idea though.

Schweet.

That’s exactly the same Ruger I got for my (patiently awaited) suppressor.

I don't know how long I will have to wait for my can, but I have a list of mods that I will be applying long before that. I even have a dummy Gemtech suppressor on order just to get used to handling properties so I don't embarrass myself when the real thing arrives.

Meanwhile, here's the results after remembering to read the instructions on zeroing the red dot sight.

Afterwards, I gave it a thorough cleanup, including giving the back of the receiver a light rap with a plastic mallet to remove it from the frame. After several dozen light raps didn't accomplish anything, I decided to go with my ultra-precise Mexican screwdriver takedown tool.

The receiver came off with the fourth solid whack. I did a bit of precision fitting with Nanolube, so the next time it will disassemble in a more controlled manner. I keep forgetting how filthy .22LR ammo is, but I'll become intimately familiar with cleaning procedures.

I also realized that the 1/2x28 barrel thread is the same as used on AR15 barrels. Just for grins, I put on the Noveske "flaming pig" flash hider for this photo:

After I install the trigger mods, I'll be doing a lot of testing with every brand of subsonic ammo I can get my hands on. Meanwhile, I'm debating getting a threaded barrel for my Walther P22.

I can hardly wait until the gun grabbers discover this "loophole", and have multiple cows.

I can't speak for the real thing, but they sure have lightning-fast delivery of a dummy Gemtech suppressor.

This edition of Saturday Night Gun Pron, posted, as usual on Sunday morning, is the first for 2012. Best wishes to everybody for a year better than 2011. Please forgive me if it takes four months for me to start writing "2012". :)

More baby steps on the long road to achieving a real suppressor on my Ruger 22/45. But that's okay, because I have a lot of work yet to do on the pistol itself. Most of it involves undoing the "improvements" that Ruger's product liability lawyers put into the Mark III.

First, new results after the aftermarket kit got rid of the magazine safety mechanism. It basically turns the Mark III into a Mark II, but at extra cost, and some user-unfriendly gunsmithing. Here are the first results with a trigger that is more normal for a Ruger .22.

The target on the left was made with RWS subsonic ammo, the one on the right with Remington. At seven yards, the Ruger should be able to chew out the "X" ring with 50 rounds, so we're mainly looking at my current level of skill.

Still, the results came with the much-improved trigger pull. These were the parts I exorcised from the original configuration.

On the left are the hammer, disconnector, bushing, and fiendish spring of the original. That dark smudge on the side of the hammer is powder fouling being ground into the precisions surfaces of the hammer by the disconnector parts. It works well if you're aiming for a lousy trigger pull to go along with the false sense of safety a magazine disconnector brings.

On the right is the original main takedown pin. The new two-piece one makes quick cleaning actually quick, and a total takedown marginally less agonizing. The conversion took about two hours of trying to stuff five pounds of parts into one pound of handgun, but now that it's done, it doesn't need to be done again. I would recommend three extra hands for anyone considering doing it themselves.

St. Barbara must have taken pity on me, because my next project, done on a whim, went so smoothly I was done before I realized it. On a hunch, I thought the Magpul mid-length MOE handguard would work on the M4P(piston), and would look and feel much better than the factory one. A half-hour of careful grinding of the guide ridges inside the front of the upper half of the handguard left things a perfect fit. To top it off, the lower half then fit perfectly with no effort on my part.

It's slimmer, trimmer, and feels better than the original. I think it also looks more sexy, almost like something off a FAL, which, being ancient, still gets high marks for exotic beauty. Of course, I had the benefit of my specialized handguard fixture and removal tool, which were the equivalent of five extra hands. This isn't the first time that my $100 investment in tools saved me a million dollars of grief. It was so easy, I'm almost tempted to do it again.

And for a second easy project in one week, I installed a threaded adapter on my Walther P22, awaiting the day when I can put the real thing on it. Some of the newer .22 pistols, like this Walther, and the Sig Mosquito, use the new euro-style "tension" barrels, where a front nut compresses a sleeve around the thin rifled liner, providing "tunable" stiffness to a light weight barrel that would previously needed a heavy barrel to do the same thing.

In this case, all I did after unscrewing the standard barrel nut was to put on the threaded one. Finding the special wrench was a bit of an adventure, but that was my own fault for forgetting where I put the important stuff so it won't get lost. It wasn't lost, but it took me about two hours to find it again.

The Ruger with the dummy can attached looks like "business". On the Walther, it just looks and feels "cute".

And yes, the sights are still high enough to work with the suppressor in place. Now to see how the Walther likes subsonic ammunition. It wasn't very fussy with the regular stuff.

For the first time, I went away from home for Christmas.

(I've been away before-- during my Army years-- but this is the first time I ever went away on my own, on purpose.)

MrsEx has an old, dear friend who lives in Virginia. She and her husband usually go to Myrtle Beach, SC for Christmas (their only "kids" are a pair of schnauzers). This year, they invited us to join them.

We visited Appomattox Court House, Virgina (where Gens. Lee and Grant met):

Then, a five hour drive later:

View from our balcony Christmas morning:

Church:

Back at home now.

It was fine, and I like MrsExs friends (not so much their dogs!)-- but I told Mrs Ex "no more beach vacations in winter".

Since no one else will claim ownership of the Great Roll of the Shire (aka The Hobbit Hole Ping List), I have cobbled together a list from memory and some searching.

If you have been pinged, and would rather not, please say so here or by FReepmail.

If you know of anyone I have left out, please let them know and have them say so here or by FReepmail, that I may grovel appropriately and add them to the Great Roll.

Hi Dolly, it’s good to see you again!

Folks, Dolly and I were able to meet and moot while shooting cowboys in October.

I’m not positive, but I think Dolly snapped the photo in post #3631.

Happy New Years Win-Mag. We’re all hoping that 2012 is better than 2011. Still for the high points and low points, we’re all still here.

The new Ruger is SU-WEET. The fake suppresor looks like the real deal, that alone should turn some heads at the range. I know it would around here.

Yep, the Rugers will test anyone’s patience when it comes to take down and ‘reassemble in reverse order’. The Marks I through III, folks swear by them and folks swear at ‘em. I like the CCI-standard velocity for bullseye shooting; plates and pins get Federal bulk pack. Some are using CCI-Blazers and report good results.

One thing you can say about the Rugers, there is a heap of aftermarket goodies available to customize both internals and externals to one’s hearts content. Needless to say, I’ve been tempted.

Morning - sounds like a nice mid-winter break, especially without the snow. The whoosh-woosh of the waves is pleasant anytime. I spent quite a bit of time in Mrytle Beach in the late 80s working. Nice place, in the off season.
