SR-25 E2 CC M-LOK - Knight's Armament

SR-25 CC, M-LOK

PN:31893

The SR-25 Combat Carbine is equally adept at putting rounds on target past 800 meters or rapid multishot 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.

5R Cut 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.

Multilog E2 Bolt

The E2 bolt design improves function and offers extended lifespan. Dual ejectors provide significantly increased ejection force, ensuring that the cartridge is cleanly ejected from the ejection port, even when using high backpressure muzzle devices and collapsible stock systems, and provides a layer of redundancy in the event of failure. The bolt lug design has been optimized and stress-relieved, extending overall lifespan to not less than 10,000 rounds. The E2 bolt is completely backward compatible with M110 barrels and bolt carriers, and utilizes many of the same parts as the legacy bolt design.

Quick Detach Coupler

The Quick Detach Coupler (QDC) line of Sound Suppressors and Muzzle Devices are proprietary items designed for secure interoperability. The coupling device itself consists of multiple ball bearings arrayed in a circular pattern which fit into sockets specifically machined into various muzzle devices to accept the QDC. The bearings are aligned with the sockets by way of a V-shaped notch that seats the device onto an index pin. Once aligned, a simple twist of the outer retaining ring locks the device securely into place.

This system was developed to provide fast and easy operation and interoperability between weapons and suppressors. Knight's QDC line of sound suppressors all feature this method of attachment. Various muzzle devices, such as the QDC Flash Suppressors and the MAMS muzzle break, also feature the QDC pockets to accept sound suppressors equipped with this coupling device. Secure interoperability and intelligent, efficient design are the intended goals of this quick and easy technology.

Ambidextrous Controls

Knight’s Armament designed this system to give shooters the maximum amount of options in their controls. Under this design all of the weapon’s major controls can be accessed from either side of the lower receiver. Left-handed shooters see the immediate benefits of being able to access the weapon’s controls in a more intuitive manner; however, there are a number of other benefits that right-handed shooters will enjoy under this system.

Competition shooters benefit from these controls from the increase of speed that is achieved through components such as the right-side bolt catch. Trainers enjoy the variety of options because they can watch their trainee from either side of the weapon and even manipulate the weapon’s controls from the non-operating side. KAC has also introduced modifications to the design such as the scalloped safety selector switch. This allows a lower profile for the selector switch on the non-operating side of the receiver which helps to relieve any interference between the switch and a shooter’s glove or hand. For the maximum amount of configuration and operation options, Knight’s Ambidextrous Controls offer a sure solution.

Stage Match Trigger

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.

MLOK

M-LOK is a modular locking accessory mounting system that is a direct attachment method for hard mounting accessories to a negative space mounting point. The M-LOK attachment system allows the user to put mounting rails only where they were needed, as opposed to covering the entire surface with mounting rails, which are then covered with panels. The system also allows direct mounting of accessories, such as fore-grips and flashlights, with no rail interface needed.
