CMMG 22LR AR Conversion Kit, Echo, LH, 10rd, BLK

22LR AR Conversion Kit, Echo, LH, 10rd, BLK

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. Compatible with left handed 5.56/.223 chambered upper receiver groups. Ships with a 10rd Mag.  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 our 22LR conversion kits
