CMMG 22 LR conversion

[Gabriel]

These an good? I know it's a general question, but Primary Arms is having a sale on them and I happen ot have a spare AR that I wouldn't mind converting to 22 since I don't do anything else with it. It is 1/7 twist, though. I was wondering if the conversion would make it a good little accurate rifle, or if the conversions have inherent accuracy flaws and are just for general plinking to save money on 5.56.

I picked up a conversion kit from the classifieds a few years ago... IMO- They are good for plinking. They like hotter .22LR such as M-22.

If the price is right, they are fun.

YMMV.

They have it for $129 with one magazine for anyone interested.

Conversion kits installed in NATO barrels are kinda crappy. They would be okay for close-in room clearing drills or something, but at any distance, the 7-twist fairly well sprays targets of any kind.

Have you ever put a brick through an AR with one of these units? Trust me, if you're going to go to the trouble of recleaning the ENTIRE lower of all the carbon, wax, unburnt powder, primer residue, etc... you'd really like the rifle to perform.

Now then. The CMMG conversions, stripped down, and installed in DEDICATED uppers are a different story. THOSE are awesome.

Functionally, there's never been anything wrong with the CMMG etc. units. The issue is the barrels they are installed into as conversions, and the fact that the bullet has to jump ~1" through that chamber adapter before it starts engraving....and .22LR doesn't tolerate that very well.

For the price I think they are generally good. If you plan on shooting a lot or want more accuracy, get a CMMG or Tacsol complete .22LR upper. I have a CMMG and it is totally reliable, shoots around an inch or so at 50 yards and converted my nephews to gun nuts.

I've had one for a couple of years and it's always run well as long as I keep it somewhat clean and lubed.

The one thing you will have to worry about is that the bolt is a direct blow back operation. So, you might have some malfunctions in cycling with any gas that goes through the gas port into the tube.

Thanks for the replies. It looks like it isn't quite what I am wanting. Maybe a dedicated upper at some point would be better.

I know I have a dedicated barrel that I bought when I was going with a quick change barrel system. Now that I changed my mind on that route, I have do not need mine anymore.
