The SR-25 E2 series is the latest evolution of the dual role 7.62 mm NATO Carbine. Each are equally adept at putting rounds on target past 1000 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.
All of the weapons available from Knight’s Armament come equipped with a 4.5lb, 2-Stage Match Trigger. This type of trigger mechanism uses a system where, during the rearward squeeze of a trigger, it cycles through two stages of resistance
The first stage is a ‘no-poundage’ stage where hardly any resistance is felt during the rear-ward squeeze. There is a center point at which point resistance is felt and the second stage of the trigger begins. At this point, 4.5 pounds of force is required to squeeze the trigger through the second stage and cause the weapon to cycle.
Our 2-stage trigger is meant to inform a shooter of exactly where their weapon is going to fire. This bolsters a firer’s confidence and can also assist in reducing trigger jerk, thereby increasing accuracy. The 4.5lb 2-Stage Trigger from Knight’s Armament is a highly calibrated and smooth component that is sure to be a welcome addition to any setup.
5R Rifled Barrel
5R is the form of rifling developed by Boots Obermeyer for use in most target barrels and in many sporting barrels. These barrels have 5 grooves, and the lands have angular sides. It has been observed that bullet jackets will deform such that they remain closer to the R-form lands than they will to the sharp-edged lands present in conventional-style rifling. This reduces powder fouling at the corner of the grooves. The angled form of the lands also helps to reduce jacket failures in quick-twist barrels
