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
