“US Army Preventive Maintenance Manual for the M16A1 Rifle, published by PS Magazine in a comic book form. The idea was that young, uneducated soldiers were more likely to read comics than boring military manuals. This one was illustrated by the prominent comic artist Will Eisner.”

I've got an AR with the CMMG piston kit and one with the Adams Arms kit. Both work just fine, but for the mount it and forget it factor, I would go with the Osprey Defense system in a heartbeat. I've shot 75 grain all the way down to 52 grain ammo through the rifle and not a hiccup. I even loaded different weights in the same mag and had zero issues firing the entire mag. One caution: I put the Osprey on a 14.5 inch barrel gun and had to remove half a loop from the recoil buffer spring to function perfectly. I'm running a Lavange flash suppressor, welded on, and am tickled pink with it. Gun doesn't weigh much more than a loaded 1911 with a thirty round mag 5.56 in the AR.
Short of buying a SCAR 17, this is the best solution to the AR/M4 dirty dump in the bolt problem I can imagine. I've seen no evidence of carrier tilt/drag, so far.
PS Magazine was an excellent way to get MWO’s, tips, and updates into the hands of the troops in a timely manner. It was a regular maintenance pub that covered all kinds of Army equipment; not just the M-16.
And a lot of good, sometimes hard-to-find National Stock Numbers to order nice to have goodies for the field. Supply Sergeants loved them.
bflr
I forgot to mention that retro fitting the Osprey onto an existing impingement gun is a snap.
Don’t know too much about firearms, do ya?

That was a requirement to pass boot camp in '74. I remember it was a timed test.
As it was for us in the Army, in Armor AIT, circa 1968.
Then I got to my first line assignment, where we learned to do it again. With a M1911A1 .45 pistol, an M3 greasegun, a M73 co-ax machinegun and an M60 MG, all taken down and all the parts in one pile.
That took a little longer....

Piston guns are good.... Hk 416 is a great design. Glad companies are using the design for us retired folks semi-auto variants.
Hope you’re well !
I didn't know they had eyes.
Rolling right along! The lastest build and probably my last 5.56 build is very lightweight, and sporting a piston system which appears for all the world like it is self cleaning! ... I’ve shifted into shotguns and modifying twelve and tweny gauges for home defense weaponry. Working on a new size shell to allow an extra round int he tubular mags, enjoying my Lee Load-All II in 20 and 12. You getting any shooting in?
I’d never seen one of these before.
Also, what is going on with the 6.5 Grendel-6.8 Rem options? I am a big fan of 6.5 stuff, having been killing things, including big things, with my trusty surplus Swede Mauser since they were available mail order back in the pre-Kennedy Jurassic Era.
BTW, I would think a 300 AAC would be a better transition round since existing mags can be used after switching the barrel/firing chamber out.
You can swap uppers easy to any. Caliber piston or not. Works very well grendel or 5.56 etc...
My favorite carbine is a 96 mauser as well KB. Paid 80 dollars for it an a old SF armorer had cut it down to carbine lenght bbl aka 18.5 inches. Added a cheap 6-18x tasco snagged at big box store for 20$ and a sling from an old garand made this a 100$ favorite. Favorite OTC load is 140 gr Alaska Norma makes. They have a heavy 156gr also but the 140gr is most accurate in my kitchen bench carbine.
Stay Safe !
Have fun!
Have you seen or heard of piston driven systems for the AR scraping the lower receiver at the rear, prior to going into the buffer tube on recoil? The “word” is that bolt carrier tilt can be an issue. I’m still holding off for the time being, but was strongly pondering the kit by CMMG. :-)
CMMG makes a good system, better than the Adams Arms system. If you intedn to shoot a lot of 22lr practicing with your weapons platform the CMMG is the way to go because it is easy to trun off the gas system and use the stainless CMMG carrier and bolt insert for 22. Their customer service is exceelent, too. I've used it and can vouch for that aspect. Osprey Defense has excellent customer service response, also. The problem with the Osprey trying to use the 22lr inserts is tht the gas system is a bit more difficult to disconnect, but it can be done by removing the handguard and taking the retainer clink off of the piston rod then removing the whole psiton from the cup. If you call CS at Osprey in Fla. they will send to you an extra link clip for the piston to rod connector. Great folks down there. Once you drive the cup into the gas block you are not going to be switching it to another gun though.
I’m glad I asked because I do in fact have a CMMG .22LR conversion kit and we like it a LOT. Thanks for the advice! :-) I appreciate it!
