Faxon Duty Series 10.5" SOCOM 5.56 Barreled Upper (FX-URG-D556105SA9-BU)
Build a compact, battle-proven AR-15 pistol or SBR with the Faxon Duty Series 10.5" SOCOM 5.56 Barreled Upper—a factory-assembled barreled upper designed for tactical, duty, and defensive roles where heat management, sustained accuracy, and reliable short-barrel cycling are essential. This barreled upper includes the heavy SOCOM-profile barrel, enhanced forged AR15 upper receiver, fixed low-profile gas block, carbine-length stainless gas tube, 9" M-LOK handguard, and A2 flash hider—ideal for close-quarters use, vehicle defense, high-volume training, or any setup needing rugged performance in a short package (requires BCG, charging handle, and lower to complete).
Centered on a Duty Series 10.5" SOCOM-profile 5.56 barrel (4150 CrMoV steel, black nitride QPQ finish, 1:8 twist, carbine-length gas), paired with Faxon's enhanced forged AR15 upper receiver and modified feed ramps for consistent feeding. The fixed .750" low-profile gas block and carbine-length stainless gas tube ensure dependable function in short barrels, while the heavy SOCOM contour manages heat and reduces mirage during rapid or sustained fire. The 9" Streamline M-LOK handguard provides lightweight modularity, and the A2 Bird Cage flash hider delivers effective flash suppression. Made in Greater Cincinnati, Ohio with Faxon's lifetime warranty.
