There are many reviews of the CMMG 22 long rifle conversion kit on Youtube, but I’ve tried to make the most comprehensive one on the topic. It’s longer, but I think worth it.

Over the course of the last three years, i have put between 4 and 5k rounds through one of these in three different uppers. The 1/7 twist barrels were much less accurate past 25 yards than the 1/9 that I subsequently prefer to use. The worst issue i have had, after 500+ rounds, the gas block and the tube get completely filled with filthy .22 residue that gets blown out by standard 223 ammo, filling the bolt carrier, and welding the gass rings to the bolt. After this happens, you might need to replace the gas rings, as they will likely break during removal for cleaning. This may not be an issue for all uppers, and might depend on the location of the gas port either in a land or grove of the rifling. It has happened to me twice, and everyone should be aware of this possibility.
I took a co-worker to the range after he told me he though the "AR" in AR-15 meant "assault rifle." I showed him how to safely operate and handle the rifle, how to load the magazine. Then sent to the 25 yard line to set up the target. While he did this I swapped out the standard bolt for this, CMMG conversion bolt, loaded and put on the safety. When he returned I showed him again how to turn off the safety and how to should the rifle, where to put the red dot. I then stood behind him with my hand pushing on his shoulder, which caused him some concern regarding the recoil. After he fired the first shot the look on his face was priceless. Take your anti gun friends to range and let them shoot your scary black rifle. It's fun.
Outstanding video. This was exactly the detailed info I was looking for about the CMMG .22lr conversion kit.
Love mine! Runs everything I feed into it. Your findings are about the same as mine. Winchester white box runs too. Anything high velocity with the occasional hiccups as you showed. Cci runs near flawlessly, of course.
Great vid! Long runtime too, dig it!!
Very much enjoyed this video, Well done and explained.
My only issue with that is potentially carbon fouling so I'd keep spare gas tube
This sure did help tilt my purchase decision for one of these. Thank you, 8mm Mauser Man!
