KK-Wechselsystem CMMG 22LR AR Conversion Kit, BRAVO, Kaliber .22lr

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 3 25rd magazines.  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 22LR conversion kits.
