Knight’s Armament Company (KAC) had a number of interesting items at their booth at SHOT Show 2007. For the purpose of this article, however, we’re going to focus on their 5.56x45mm NATO (5.56mm NATO)/.223 AR-15/M16/M4/M4A1-type, semi-auto only KAC SR-15 (Stoner Rifle 15) Rifle/Carbine and select-fire/full-auto KAC SR-16 (Stoner Rifle 16) Carbine/CQB Carbine. The “CQB Carbine” is basically a SOPMOD M4 CQBR(Close Quarters Battle Receiver)-type subcarbine/SBR (Short-Barreled Rifle).
The SR-15/16-series weapons packages sport a bunch of “whiz-bang” features, including…
forged receivers (upper and lower), improved multi-lug E3 Bolt (for “enhanced reliability, durability, and maintainability”), ambidextrous controls (including safety/selector switch, magazine release button, and bolt carrier release button), KAC URX MWS (Upper Receiver Extending Modular Weapon System) Mil-Std-1913 “Picatinny” Rail System (a.k.a. “P-Rail”) / forend rail tube, and front and rear KAC flip-up BUIS (Back-Up Iron Sight) system. All of these components are included in the package.
A unique aspect of the KAC integral front BUIS is that it incorporates a Mil-Std-1913 rail surface and blends perfectly with the rest of the URX top rail when it’s in the down position. Nifty little feature.
The patented ambi-controls are the main separating feature, though, when comparing the SR-15 series and SR-16 series weapons to other manufacturers’ AR-type weapons. These additional controls are well-executed and integrated.
These weapons got a lot of attention at the KAC booth. It will be interesting to see how tactical professionals (Mil/LE/PSC/PMC) and civilian tactical shooters respond to the ambidextrous controls over time. Defense Review is also interested to see what 3-gun tactical match shooters think of the ambi-controls, and if this new aspect changes their weapons handling processess/procedures during matches.
