AR-15 AP4 A3 Conversion Upper Receiver Assembly 22 Long Rifle 16" Barrel
This DPMS AR-15 AP4 Upper Receiver Assembly is a complete, dedicated rimfire conversion upper in 22 Long Rifle that is ready to install on any standard small pin lower receiver. It features a proprietary rimfire bolt assembly, true 22 LR chamber and correct 1 in 16" rifling twist, all of which ensure an accurate, reliable upper that is perfect for inexpensive practice, small game hunting, or introducing young or new shooters to the AR-15 platform. For useful, realistic sub-caliber training purposes, this upper offers the familiar operating controls and handling characteristics of a full power AR-15, but without the associated high priced ammunition.
The Forged 7075-T6 A3 Upper comes equipped with a Flat-Top Picatinny Rail for mounting optics, 16" Chrome Moly M4 Contour Barrel, Carbine length GlacierGuard Handguard, functional ejection port door, A2 front sight assembly with bayonet lug, A2 flash hider, charging handle and one 10-Round Black Dog Magazine. This upper is compatible with Black Dog Machine and CMMG rimfire magazines, and is 22 Long Rifle specific, meaning the upper cannot accept bolts, carriers or barrels in any other caliber. Different handguards designed for centerfire AR-15's are compatible.
