Knight's Armament KAC SR-15 KS-2 14.5" CHF 5.56 NATO (SBR) Short Barreled Rifle

Knight’s Armament SR-15 KS-2 14.5" CHF 5.56 NATO SBR Rifle – For Sale at BattleHawk Armory

The Knight’s Armament SR-15 KS-2 14.5" 5.56 NATO SBR represents the next evolution of the legendary SR-15 platform, blending Knight’s proven combat performance with meaningful modern enhancements. Built around a 14.5-inch cold hammer forged, chrome-lined barrel and the updated URX 6 M-LOK handguard, the KS-2 delivers a lightweight, hard-use short barreled rifle designed for duty, defensive use, and serious enthusiasts who demand top-tier performance.

Now available for sale at BattleHawk Armory, this premium SBR is engineered for shooters who refuse to compromise.

At the heart of the KS-2 is Knight’s Armament’s advanced E3.2 bolt system, engineered to exceed the durability and reliability standards of conventional AR-pattern rifles. The enhanced round-lug bolt design improves bolt life, while the lobster-tail extractor and dual ejectors promote strong, consistent extraction and ejection—especially in suppressed applications. Combined with Knight’s proprietary mid-length gas system, the KS-2 offers smoother recoil impulse, excellent reliability, and extended component life.

The fully ambidextrous lower controls give both right- and left-handed shooters fast, intuitive manipulation of the bolt release, magazine release, and selector. A factory two-stage trigger provides a refined break for precision shooting while maintaining speed for close-range engagements. Up front, the KAC 3-Prong Flash Eliminator reduces flash signature, eliminates ringing, and is fully compatible with Knight’s Armament 5.56mm QDC Signature Reduction Devices.

With its premium materials, refined operating system, and battle-proven Knight’s Armament pedigree, the SR-15 KS-2 14.5" SBR stands among the finest factory SBR platforms available today. Available now at BattleHawk Armory—your source for high-end firearms and elite performance gear.
