Q
Donny, member, from TX, United States, asked on June 11, 2020

Does this barrel work with the CMMG 22LR Conversion Kit bolt group?

A
Answered by John, guest, from SD, United States, on June 19, 2021

With some mods, yes. You would need to change out the chamber adapter from your bolt group, to the barrel collar that CMMG makes for these. The collar lives on the bolt carrier assembly, but it can be installed just like a 5.56 BCG, all together from the rear of the upper. Do it, you will be so happy. I did it because I got tired of cleaning my 5.56 chamber, and star chamber locking lug teeth. 22 shoots dirty, and a dedicated 22lr barrel makes cleanup waaaay easier. Hope this helps!!

What muzzle break do you recommend for this barrel?

Expert Answer
A
Answered by Hunter, Gear Expert, from OH, United States, on September 28, 2022

The CMMG, Inc Barrel Sub-Assemblyy, 22LR, 16in barrel is threaded for 1/2x28. So a standard AR15 5.56/.223 muzzle brake will work. The muzzle brakes at the link below will work.

Yes. The CMMG, Inc Barrel Sub-Assemblyy, 22LR, 16in barrel will be able to utilize any free float handguard. It does not require a gas block, so slim-line handguards will fit and function without issue. This barrel also Includes a barrel collar to replace the chamber adapter on your 22AR Conversion.
