Knight's SR-15 Light Precision Rifle(LRP) is the answer for shooters who seek a lightweight match weapon system. The LRP utilizes a Match Grade Stainless Steel barrel with a custom match chamber and 556QDC Flash Eliminator. Additionally the LRP features the URX4 with M-LOK compatibility, Mod 2 Gas System, 200m-600m micro sights, Magpul SL-S stock and ambidextrous lower receiver.

An improved E3 round-lug bolt design both enhances function and increases bolt life far beyond the industry standard. The ambidextrous bolt release, selector lever, and magazine release offers 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 SR-16 LRP is equally suited for competition or precision perimeter use.
