CNMG AR-15 .22 L.R. Conversion Kit ??
« on: July 26, 2021, 12:56:25 AM »
Do any of you guys have one? If so how do you like it? I ordered one the other day, and it's scheduled to arrive this coming Wednesday on the brown truck. I bought the "Bravo" model with 3, 25 round magazines. $180.00 + Tax and shipping. Not too bad. I got it from Primary Arms. They shipped it within 2 hours.

I've watched a bunch of videos on You Tube, and most seem pretty happy with it overall. The AR twist rate, (1 in 7"), over spins the .22 L.R. bullet by a factor of over 2 to 1, but even so it doesn't seem to deter from accuracy too much. Most of them group pretty well. At least from the demonstrations I've seen.

And the only way you're going to get around the twist rate, and get a 1 in 16" twist barrel, is to go with a dedicated .22 L.R. upper. And for a good one you're looking at $500.00 or so. I didn't want to spend that much, because this is more or less a SHTF purchase, and a way of making all of my AR's able to fire .22's.

I know Ciener makes one, but I've heard that guy is nothing but trouble to deal with. I don't even know if he makes them anymore. I have a Beretta .22 conversion for my Beretta Model 92 FS, and it runs well. So I'll be looking forward to trying this one out. You guys chime in if you have any advice on ammo. It says they run best on Federal Copper Plated Hi-Speed Hollow Points. And I have literally dozens of 550 round, "Bulk Packs" of that stuff.

I love them, I have two.  I got my first one way back when BHO was prez during an ammo shortage.  I was able to continue to train with cheaper ammo. 

I don't notice an accuracy issue but then I only use it for training.  I'm not shooting for tiny groups.  Sometimes I run one with the can on.   

I've seen AR pricing start to relax a bit from the highs so maybe you can dedicated upper before too long.  However, with the idiots we have running everything the prices may never return to where they were.

If you can find any try the Aguila .22 SSS (SniperSubSonic) It's a 60 grain bullet that should work well in a 1/7 twist barrel.

They are quiet.  I bought a few boxes in the early 2000's...still have most of them.  Not accurate past ~50' in my guns.

They had some in stock here, not cheap, but available.

In a standard .22 rim fire barrel they will keyhole past a certain distance, But should be fine in an AR-15 barrel.
