Barrel and Bolt Group Kit 22 LR

 

Everything you need to convert your existing upper to a dedicated .22LR. Just purchase a magazine and you are ready to go. For best performance use a round style hammer as notched hammers can cause function issues and 36 grain plated nose bullets have proven to be the best choice for function.

All CMMG products come with our Lifetime Quality Guarantee.
