Wolf Performance Arms Offers Shooters the finest and most reliable AR-15 piston driven barreled upper produced in the world. The Wolf A1 upper features a short stoke piston system, unsurpassed durability and reliability for functioning parts and action while confidently maintaining performance under adverse weather and climatic conditions. Additionally the uppers have superior ergonomics for both comfort and tactical applications. The Wolf A1 upper is the premier choice when it comes to home defense, recreation, hunting, and tactical applications. For use in pistol configurations or with registered SBR lower receivers.
The Wolf Performance A1 Complete AR-15 Upper Receiver provides shooters with all of the benefits of the standard AR-15 upper, which can be easily paired with any lower, while offering increased reliability over more common direct-impingement designs. This complete upper is based on the design of the T91 rifle from Taiwan and offers the added reliability of a short-stroke piston system, which doesn't direct debris and other harsh byproducts of cartridge ignition back into the receiver, ensuring that nothing impedes the reliable performance of your rifle.
