CMMG perfects the drop in AR .22 conversion.

[HBARleatherneck]

i bought my cmmg kit with 2 blackdog mags for $125 on coloradogunmarket.com

i think Bob Jensen was selling them for $150 new. probably with 1 mag, but i am not sure.

i still use the 10/22 most. ultra reliable, accurate.

my .22 conversion kit for the AR...not terribly reliable. lots of jams.

Right here is exactly my point. Sure you can adapt an existing rifle to do this but my experience has been that the reliability decreases substantially. This was my reason for asking why not just get a rifle that was designed for that purpose? From some of the statements being made I think it's a fair assumption to say that those that are so against it haven't fully researched the newer stuff that's out...namely the M&P15-22. I'm not a fan of some of the other offerings for many reasons but this rifle really got it right IMO and fills that need perfectly.

Jams as in spent casings stuck in the chamber? If so, I had that prob as well. Check your extractor. If a round won't stay on the bolt face when you turn it horizontal, replace or fix the extractor. Once I did that reliability went way up.

I'll go as far as saying that I haven't found a conversion kit for any firearm that I like. All of them lower the reliability of the firearm and all of them are a bandaid fix for the real solution... a dedicated firearm built from the ground up for the caliber intended. This has been my experience across the board. Maybe you have different experiences than me that changes the outlook on this topic. That's all I'm saying.

Uh, I think we're confusing bad design with mechanical malfunction. I never had any problems with my conversion bolt. My dedicated upper had issues because of a bad extractor. And we are talking .22s here. Even the famed 10/22 will have a jam once in a while. semi-auto 22's as a class aren't known as fail-safe firearms. They're fun plinkers or training aids but not SHTF weapons. I like .22s because their fun and cheap to shoot, but I would never rely on one for my life.

I don't plan to trust my life to one either but that doesn't mean I don't want it to work. Every conversion I have used has caused issues of reliability and by that I mean bad design that causes mechanical malfunction. They aren't independent of each other in this discussion. I have a Glock 17 that has eaten literally tens of thousands of rounds of 9mm of any and all varieties and I never had problems with it. I have tried several different fancy .22 conversion kits for it and it's always the same thing... I spend as much time clearing malfunctions, identifying issues and taking things apart as I do actually shooting the damn thing. Same thing goes for AR15 conversion kits and others that I have tried. Personally, I really don't like using 'conversion kits' for anything because my experience has been that they are more trouble then they are worth.

So, to recap:

Glock 17: not problematic, fun and worry free to shoot
AR15: not problematic, fun and worry free to shoot
AR15-22: not problematic, fun and worry free to shoot

Glock 17 w/22 conversion: numerous malfunctions & FtF w/lots of frustration as a result. Fun to shoot when it works though.
AR15 w/22 conversion: numerous malfunctions & FtF w/lots of frustration as a result. Fun to shoot when it works though.
