Has anyone bought the .22lr conversion kit for AR-15 rifles and how do you like it? Is the 195.00 cost worth buying?

"The .22 conversion kit?" There's a BUNCH of them available. I have a spikes conversion and it's well worth the price. Fun to shoot with the kids.

I have the ciener kit with the 25 rnd Blackdog mags, I absolutly love it. I shoot more in 22 then I do in 223. Very little to no recoil, very quiet, very accurate.

I just tried out my CMMG conversion kit and it was flawless with bulk federal ammo. Had a ton of fun for very little cost.

CMMG have really improved the design in the past few months...adapted it to use a bolt hold open, forward assist, and all sorts of other additions that make it a more viable training alternative...

My Magpul BAD is holding the bolt back on here with the recent adapter they released:D

Yes, I've used the Ceiner and CMMG conversion. Both worked well for me.

Couldn't get the accuracy I really want, but that is because of the tight twist of the barrel. If you want to put five shots into a postage stamp at 25 meters you need a dedicated 22lr upper with a proper 1:16 twist. I don't know if an older 1:12 twist would work any better, but I used a 1:7 and 1:9 and both were about the same.

But if you want to ventilate soda cans, they work very well for that.

I had a USAF 22 subcal kit for the AR for over 20 years..it was to me the most reliable but the ten shot magazines sucked. Had a couple of the ARMY subcal units... OK , some of their mag inserts were junk. I traded them off beofre BLack dog machine made high caps for them.
I got CMMG kit a year ago..it's identical to the ceiner kit so it's been subbed out from Ceiner. It's OK , not as reliable as the USAF kit , the early 25/27 round mags with these wear out too quick ( plastic bolt hold open follower junk ). Tweaked it out a bit and got a black dog 50 round drum and it seems to be a bit better. Most of the problems I have with the CMMG kits are light firing pin hits and it's lack of positive extraction of fired and unfired rounds.

Jimro ; My A1 upper does incredibly well with the subcal in regards to accuracy. So , yes the 1/12 twist makes a big difference from the compromise 1/9 and the A2 1/7.
