Cmmg .22lr Barrel & Bolt – 4.5″
$299.95
Barrel and Bolt Group Kit, 4.5″ MT 4140CM, 22LR
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.
