The Knights Armament SR-25 E2 series is the latest evolution of the dual role 7.62 mm NATO Carbine and Rifle. Each are equally adept at putting rounds on target past 800 meters or rapid multi-shot engagement at close range, with a barrel and bolt life to support the training regimen necessary to master these skills. An ambidextrous bolt release, selector, and magazine release offer the left-handed user the ergonomic advantages inherent to AR15 based controls, as well as giving right-handed users alternate methods of manipulation to increase efficiency of movement. The drop-in 2-stage trigger serves double duty as an aid to long range precision marksmanship while enabling surgical speed shooting at close range. A 7.62 QDC Flash Suppressor reduces flash and ground disturbance, and supports KAC QDC Signature Reduction Devices.
