The SBR8 Complete Upper Receiver is an ideal start for an AR-build intended for suppressed shooting. Its 8-inch threaded barrel is recessed into a 12-inch MCSR handguard to accommodate the use of a suppressor, and is made from high quality 416 Stainless Steel. The handguard features MLOK attachment points for lights/lasers and grips, a full-length picatinny rail for optics and iron sights, and lightening cuts to reduce weight and help vent off the heat generated from extended firing. To ensure smooth cycling with a suppressor, the SBR8 Complete Upper Receiver is equipped with the Seekins Low Profile Adjustable Gas Block, allowing the operator to finely tune the rifle’s gas system for enhanced reliability. In addition, the SBR8 Complete Upper Receiver is outfitted with the Seekins DNA Charging Handle, which offers a wider gripping surface as well as a Diamond Coating Texture to ensure positive manipulations in adverse conditions.
