Colt LE6944P Monolithic Piston 5.56 NATO 14.5" Upper Receiver Conversion Kit

Colt Firearms LE6944PCK Frame Features The Colt LE6944PCK conversion kit is built around a 14.5 government profile steel barrel with a 1:7 twist rate a combination that stabilizes both lightweight and heavier 5.56 projectiles for versatile use across training and duty-style applications. The carbine length gas system cycles the action reliably across a wide range of ammunition and the 1/2x28 threaded muzzle arrives fitted with an A2 flash hider to control muzzle flash and manage recoil impulse. A manganese phosphate finish coats the barrel steel giving it strong resistance to corrosion and abrasive wear during repeated use. Because the kit ships as a complete upper assembly with a mil-spec bolt carrier group included it drops onto a compatible AR-15 M4 or M16 pattern lower without requiring separate parts sourcing. The quad Picatinny rail is machined from aluminum and wraps the handguard on all four sides giving the end user continuous mounting real estate for optics lights lasers and vertical grips without needing separate rail sections. That aluminum construction keeps the overall assembly light relative to a comparable steel-railed setup which matters when the upper is paired with heavier optics or accessories. The manganese phosphate finish gives the barrel a dark low-reflectivity surface that suits both range use and more tactical-minded builds. Built on the Colt AR platform with mil-spec internals the LE6944PCK gives builders and armorers a drop-in path to a 14.5 configuration for sale at ARMSAGORA.
