CMMG 22LR AR Conversion Kit Echo

Just swap this drop in conversion with the bolt carrier group from your 5.56/.223 chambered rifle and you will be ready to shoot .22LR.  Ships with 25rd 22LR magazine.

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.

• Since .223 WYLDE is NOT a mil-spec chamber, we cannot guarantee fit or function with CMMG 22LR conversion kits
