Looking at the CMMG kit but wanted opinions from you fine gentleman before pulling the trigger.
Definitely the CMMG kit. It is also one way to shoot the 60gr Águila SSS. It is super quiet with a silencer.
Thanks. I was wondering about that last bit
They are great conversions, but keep in mind that the bolt is not full auto rated. So if you use it with a binary trigger or FRT, it may not hold up. A friend had his bolt crack from using it a lot with a binary trigger. My brother also has the CMMG kit and has used it with his binary, no problems yet
I have the CMMG .22LR conversion kit and love it, but when I first bought it, it jammed a lot. I thought I had made a mistake, but I took a little light oil and put it on the followers. After working the oil into the springs a little, the magazines worked with no issues.
I also have the CMMG conversion. Saved a lot of .223/556 ammo when prices were more ridiculous than they are now.
I figure I have about 5-6,000 rounds of .22lr but only 3,000 rounds of .223 so…
And don’t get me started on my low supply of .308 (only 1,500), 9mm (2,000), or .458 (down to my last 400! Gasp!). And don’t get me started on .357, .38 or 12ga! I’m really running low, guys! Better buy a reloading setup and start making my own or something.
It seems .22lr is always available. Besides this way I can shoot at the rimfire range with my son shooting the Savage Precision. Probably even things out between us too. When I showed him the conversion kit he wanted to try it out himself right away. He watched a video and was all in.
So I guess the decision has been made. Now what about accessories for it? Thoughts there?
Ordered it. Found a good deal too.
At 25 yds it is about 5 MOA, with great reliability
I’ve read the the mods help with the groupings. 5moa is really high. I’m used to much tighter groupings with my Savage Precision. Hopefully I’ll get it tighter than that!
I purchased one and liked it so much i turned it into a dedicated 7" upper. Then I turned the other into a dedicated 20" upper. MOA is much, much better. The kit as a standalone is fine. I found CMMG uppers on sale for 22LR that made me “pull the trigger” on a complete upper
I’m hoping my 16" barrel will do ok only because my safe is getting very, very full… Lol
It will do fine for practice out to 75 yards Just make sure you either clean the gas tube & barrel REAL good when your done or change BC and fire a couple 5.56 rounds to clear. It still needs cleaned but is alot easier. Sounds like with all that money your saving on 22 you can buy another safe. I did. No shame in my game…lol
Another option is a dedicated barrel and bcg. From what I hear they are reliable and a lot more accurate due to an actual 22 barrel grooves and twist. I haven’t built one so just going on an acquaintances build and information. Not sure what mags he uses. The thing is fast and accurate.
I might just get a second upper. Or build one.
I have a CMMG conversion (including barrel) that I built into a complete rifle upper. It runs okay now but I had extraction issues with it when I first got it. I had to do a bit of work on the extractor to resolve the problem. I finally replaced it with some super duper hi-perf extractor to get it 100%. I’m a gunsmith and have tuned a lot of rimfire extractors but he geometry on the original was pretty bad and didn’t leave much material to work with. That was some time ago so I don’t know if they have fixed that problem or not, but it sort of chaffs my behind to have to replace parts on a new gun to make it work.
When I contacted CMMG about the issue, they weren’t much help. Their suggestion was to try a different ammo other than the 8 million rounds of CCI I already had in my stash. Wrong answer.
I lubed it up with Moly before slapping it in. Slides will but haven’t cycled it nor have I had a chance to.shoot it.
Might go this afternoon
Wish the mags weren’t so long. They don’t need to be since they only hold 10 rds. From the bench, it’s easy to put pressure on the bottom of the mag (since it sticks down below the grip), and it put it out of line very slightly - enough that it had function problems. Otherwise, it’s a lot of fun. I got it a few years ago when the price of the 3-mag kit was pretty good. Nowadays some people are selling the 1-mag kit only.
I did forget to mention something as well of importance. Since I have a S&W 15/22 before I tried the CMMG conversion I had a bunch of mags on hand. I’m not a big fan of the mags that come with the kit so I purchased the mag adapter from BOONIE PACKER and it made a night and day difference!!! Last round bolt hold open feature and NO issues with FTE. It drops right in the lower and makes a world of difference. Both of the CMMG uppers that have been dedicated have no issues other than defective ammo. The S&W mags work way better. Bore Buddy makes weight kits and other parts that work well with the bolt. I have purchased the insert that goes in the buffer tube to help with the bolt recoil. Both componets are EASILY inserted & removed from your standard lower. In my state I am no longer allowed to purchase certain things so being creative in my youth has allowed me to basically get a complete understanding of just about how everything works and how to assemble/disassemble anything and everything. No more of the shelf purchases unless its a Nerf gun…
I’ve had this unit in my AR-15 that I built 4 years ago. To use it, you simply take out the BAG from the AR and slide the CMMG bolt right in. It’s a lot of fun firing off 25 rounds of 22 LR. I’ve had no problems with the unit after many uses. I recommend the CMMG. Tons of YouTube install videos.
