**DUE TO THE ALLOCATED AND EXTREMELY RARE NATURE OF THIS UPPER WE HAVE IT BUNDLED UP FOR MAXIMUM VALUE - IT IS ONLY AVAILABLE IN THIS BUNDLE**
The Knight’s Armament KAC SR-15 KS-2 14.5" 5.56 NATO SBR Package with Trijicon ACOG 4x32 and RCR Red Dot is a premium short-barreled rifle setup built for shooters who demand elite reliability, suppressor-ready performance, and battle-proven optics in one complete package. Combining the advanced engineering of Knight’s Armament with the legendary durability of Trijicon, this rifle is purpose-built for duty use, defensive applications, training, and serious enthusiasts who want uncompromising performance.
At the heart of the rifle is a 14.5" cold hammer forged, chrome-lined barrel paired with Knight’s proprietary gas system for smooth recoil impulse, excellent reliability, and enhanced longevity. The updated URX 6 free-float M-LOK handguard provides a lightweight and modular platform for accessories, while the included KAC 3-Prong Flash Eliminator reduces flash signature and supports compatibility with Knight’s Armament QDC suppressor systems.
The rifle features the enhanced E3.2 bolt system with dual ejectors and lobster-tail extractor for superior durability and consistent extraction—especially in hard-use and suppressed environments. Fully ambidextrous controls and a factory two-stage trigger provide fast manipulation and refined shooting performance.
Mounted on top is the proven Trijicon ACOG 4x32mm optic with a red chevron .223/5.56 BAC reticle, delivering battery-free illumination through fiber optics and tritium with built-in BDC holdovers. Positioned at 12 o’clock is the enclosed Trijicon RCR 3.25 MOA red dot, giving the shooter rapid close-range capability for fast transitions and CQB scenarios.
Whether for defensive readiness, professional use, premium range performance, or collector appeal, this complete KS-2 SBR package stands among the finest factory rifle setups available. Now available at BattleHawk Armory.
