From the manufacturer

A Piston-Driven Upper for Added Reliability

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.

The Wolf Performance A1 Complete AR-15 Upper Receiver 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.

Chambered in 5.56 NATO
All-black finish
Barrel length: 16.5 inches
Twist rate: 1:7
Includes T91 handguard and charging handle

The Wolf Performance A1 Complete AR-15 Upper Receiver comes complete with a one-piece bolt-carrier group and a charging handle, so it's ready to shoot right from the box.
