This SR-15 CQB Mod 2 upper from Knights Armament combines a short 11.5" hammer-forged, chrome-lined barrel with a carbine length gas system to deliver a compact yet reliable rifle upper suited for close-quarters or maneuver-centric configurations. The 1:7 twist rate supports a broad range of 5.56 NATO projectiles while the chrome-lined bore adds longevity and corrosion resistance under extended use.

The handguard is a modular KAC URX-4 M-LOK rail providing accessory mounting flexibility along the full top rail and fore-end. The muzzle is fitted with the KAC M4QD flash hider, designed to minimize flash signature without “ringing” and compatible with Knight's NT4 suppressors. The upper retains standard SR-15 controls including full-length Picatinny rail, dust cover, and forward assist and has been refinished in a taupe cerakote. No original box or accessories included.
