AR-15 UPPER RECEIVER PARTS

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.

CMMG Stainless Steel Gas tube for AR15 carbine length gas system. Includes installation roll pin.

Specifically designed for use with 22 AR-Conversions to prevent spent casings from becoming lodged between the bolt and charging handle. Nylon construction.
