The Armaspec XPDW™ Gen2 stock is an aluminum 5 position stock with hardened steel rods. It incorporates a low profile lightweight aluminum latch carrier with a steel lock engagement point. The stock can be rapidly deployed using the ratcheting system or gravity by pointing the rifle up while disengaging the lock. The XPDW™ is designed to mount directly on your standard mil-spec buffer tube with no other modifications. It also features a QD butt attachment point for your sling, is made in the USA, and has a lifetime warranty. Pat. Pend.
