Description

The SR-16 Complete Upper Receiver's chrome lined, 5.56 NATO barrel is manufactured to military specifications, and is free-floated inside a URX 3.1 handguard. An E3 round-lug bolt design both enhances function and increases bolt life far beyond the industry stranded. An ambidextrous bolt release, selector, and magazine release offers left-handed users the ergonomic advantages inherent to AR-15 based controls. The drop-in two-stage trigger serves double duty as in an aid to precision marksmanship while enabling surgical speed shooting at close range. The 5.56mm 3-prong Flash Eliminator interferes with propellant gas combustion forward of the muzzle to significantly reduce flash signature, will not ring upon firing or when struck, and is compatible with the KAC line of 5.56mm QDC Signature Reduction Devices.
