Pros and cons of .22lr AR-15 magazines – CMMG, S&W 15-22, KRISS Defiance, Black Dog

What about Tippman mags?

I got my wife the cmmg 22 kit for her ar 15..got 1 25 rd cmmg mag..and ordered a 25rd black dog..both had issues feeding..after a little r + d..i found a small piece of self adhesive felt..about 3/8 square.. applied to the front of the mag ..about 1/2 into the mag well..took up any movement..now i did it to both mags.. built by different manufacturers.. and it took right off..no failures to feed..and the mags set at the right angle of attack..trust me. My wife shoots the hell out of the thing..so i had to make it 100%..be safe

Are you running a standard ar15 bolt catch? Or one specific for 22

Are there any aftermarket mags that fit and work with the H&K 416-22lr version?

Great info, thanks! Looks like the new cmmg gen2 mags may actually have an addition that engages the bolt catch.

Good explanation. I'm building an upper too. Beyer barrel, RTB bolt, Aero upper. I hesitate to use the mag well boonie packer device since 1) you have to file it to make it fit, 2) this is a big one, I want to be able to to go back and forth between 22 and 223. I don't want to insert/pull out the Boonie Packer too many times due to possible wear since it is metal and I want to preserve my lower. Is that clip you used plastic? The piece you added to the catch, the is Catch 22v2, right? Any concern with it wearing at the lower?

so it really doesn't make a difference between steel and nylon lips

Been having feeding issues on my S&W AR 15-22 pistol since I bought it last February. It's the mags I have watched many vids on loading but still feed problems

Great video, I am working on a conversion and want to solve the magazine issue. Where did you find the mag-well dip?

Do you need that bolt catch adapter for proper lrbho function on 15-22 mags?

My m&p 15-22 mags are on back order and have been for about three weeks now I can’t find them anywhere else
