Product Overview
Product Description
The KAC KS-4 SR-15’s 16” chrome lined, 5.56mm NATO barrel is manufactured to military specifications, features a proprietary mid-length gas system that increases reliability and durability while also reducing felt recoil, and is free-floated inside a URX 6 handguard. An E3.2 round-lug bolt design both enhances function and increases bolt life far beyond the industry standard. On top of featuring a lobster-tail extractor for more reliable extraction, the E3.2 bolt features dual ejectors — ensuring positive ejection when utilizing suppressors.
A now fully ambidextrous bolt release, selector, and magazine release offer left-handed users the ergonomic advantages inherent to AR15-based controls. The drop-in two-stage trigger serves double duty as 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.
