The CMMG .22LR AR Conversion Kit Echo is a drop in conversion with the bolt carrier group from your 5.56/.223 chambered rifle and you will be ready to shoot .22LR. Includes a 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. The Echo kit includes a charging handle.
Note: Since .223 Wylde is NOT a mil-spec chamber, CMMG cannot guarantee fit or function.
