At one time, Colt AR-15’s regularly came with a .22LR conversion kit. Around 1988 I had a friendly dealer trade me several Colt H-Bars for various other guns. They all came with the conversion kits.
I only tried the .22 unit once and was pleasantly surprised how well it worked. Since the H-Bar at the time had a 1-7 twist which is way faster than the 1-16 the .22LR normally uses, the accuracy really did surprise me.
All in all tho just more trouble than I wanted to go to since I had a bunch of other .22 rifles and could really see no reason to shoot them in the AR.
It would be better to test the rifle and the shooter separately. Otherwise what should we conclude - that the kit has accuracy of 6 MOA? That would be pretty bad, unless the sound is the only desirable effect of the exercise :-)
Thanks for posting this. I was wondering about this conversion kit. It would let me shoot at my local pistol range rather than taking a much longer trip to a rifle range that doesn’t much like EBRs.
sigh.
Local gun dealer here is getting about 40 Rock River AR-15s in on a one time buy. I have to see which model it is, but I think that at $695 I’m gonna go for it.
I want an over-under .308/.22 barrel setup. Do any exist?
What I have never understood about these conversion kits is that (as you point out) they do not provide you with the full shooting experience. For example, putting one in a Model 1911 just gives you a heavy pistol shooting an anemic round. No recoil, no muzzle creep, yuck. You’re not really shooting a Model 1911.
Why do it? Yes, I know, the savings in ammo. Why not shoot less but when you do, shoot the real thing.
If the SHTF of an apoplectic nature, like maybe an EMP attack, one of the most practical guns for survival will be a 22LR. Not so much for protection of the homestead, but for hunting the small game that you will soon have to rely on for food. The large game would soon be depleted in such a global disaster, so dont plan on refer full of venison. Thats if you even have power for the refer. Rabbit, squirrel, opossum, birds of all kinds, even roaming domestic animals if it came down to it.
You could stock up on years worth of 22LR now for not that much money, and a good 22 is also very accurate and the sound doesnt travel far incase you had to do your survival hunting on someone elses land.
Bullets of all kinds will also be a top bartering item if cash was no longer of value.
The kits look fun, but they usually cost more than a dedicated .22 rifle would cost. I have always come down on the side of having two fully functional firearms rather than a rifle that can only work as a .22 part of the time.
Of course, if you live where it is really difficult to legally own more than one rifle, it would have its advantages.
Ruger SR-22. No conversion kit necessary. Costs $499.00. Can be outfitted with any AR-15 accessory. This gun is so much fun to shoot at the range, and ammo is so cheap.
I bought the same kit last month for my M&P. I only had a couple of FTF/FTE while going through about 200 rounds. I had way too much fun!!!
Add a suppressor and a box of subsonics and you’ll be very happy.
can LR be reloaded or is that rimfire?
My wife will only shoot a .22LR. I love to build AR-15’s so I built her an SP1 style rifle with a light barrel then put a Ciner conversion bolt in there. She loves it.
FTF/FTE’s are very rare with her rifle and usually occur due to a lack of lubrication. Every 50 shots or so I give it a blast of Remoil and it keeps humming along.
OK...only question the article didn’t answer for me was whether this was blowback or gas operation. I’d think there was potential for serious crap building up in the gas tube either way.
