About this upper
Brownells PSA SABRE Forged Upper (13.7 in) is an upper receiver chambered in .223/5.56 with a 13.7" barrel.
Manufacturer details
Barrel: 13.7" barrel chambered in 5.56 NATO, 1:7 twist, M4 barrel extension, and a mid-length gas system. Barrel is finished off with a PSA 13" PSA Sabre Lock Up Rail, and a JMAC GFHC-E pin and weld muzzle device.
This barrel is made especially for Palmetto State Armory by FN Manufacturing using their proprietary blend of hammer forged chrome molly vanadium that is referred to as "Machine Gun Steel" by virtue of its use in FN's M249 and M240 weapons. The hammer forging process work hardens the steel, making it more durable. In addition, the chrome process for the bore allows for a lining almost twice as thick as a standard M16 for enhanced durability.
Upper: Forged 7075-T6 A3 AR upper is made to MIL-SPECS and hard coat anodized black for durability. These uppers are T-Marked engraved.
Bolt Carrier Group: Father’s of Freedom BCG by Microbest with Sprinco Extractor Spring and Carpenter 158 MP Bolt.
