The SR-25 E2 ACC is the latest evolution of the lightweight 7.62mm NATO Carbine. The ACC projects 7.62mm NATO performance in a package of comparable weight and size to many 5.56mm platforms. Barrel and bolt life well exceed the expectation of a lightweight carbine. 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. The 5-slot flash hider reduces ground disturbance and flash, while allowing the attachment of Knight’s QDC suppressors.

 

Pressure Reduction

Our Pressure Reduction system is a feature designed to increase controllability and soften the rifle’s perceived recoil. This is achieved by employing unique lengths in our gas tubes and buffer tubes. On the 16” SR25 EC and ECC models we utilize a rifle length gas system coupled with a buffer tube that is ¾” longer than the standard carbine length buffer. In some of the SR15 and SR16 models, KAC employs a similar system of lengthened components to achieve the same result.

 

By using this setup, the energy released when firing is spread out over more time within the weapon. This helps to relieve vertical kick in addition to a reduction in the rearward recoil force that is absorbed by a shooter’s shoulder. Various parts in the weapon system also see an increase in service life under this system. Our Pressure Reduction system serves to increase reliability and decrease fouling, especially in suppressed usage.

 

Carbon Cutter Bolt Carrier

The Carbon Cutter Bolt Carrier is a system Knight’s developed to help increase reliability and longevity in our rifles, particularly while firing suppressed. The serrated edges along the carrier’s lower edges serve a dual purpose: The first is to pull away any foreign material; the second is to provide an area for lubrication to pool.

 

The weapon will cycle and physically move the bolt carrier. When this happens, the serrated edges will draw away any foreign material that builds up along its path. This helps to provide a cleaner surface for the weapon to cycle through. The second benefit to those serrations is that they provide an area for lubrication to pool. Lubrication will normally be applied across the flat surface of the carrier and wear off. The slight pooling effect gained by these areas helps to keep the lubrication from wearing off too quickly and reapplies it when the carrier cycles. The overall effect of this Carbon Cutter Bolt Carrier is a cleaner, more reliable weapon over a longer period of time.

 

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.

 

Two-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.

 

Quick Detach Coupler

TThe 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.

 

URX 4

The URX 4 is a continuous top-rail system that utilizes the Keymod mounting brackets developed by Vltor and Noveske. This rail system is built stronger and more stable than previous designs due to the absence of a removable bottom rail. The modular layout allows an end user to fully customize exactly where to place accessories without the use of specialized tools, small parts, or additional forces applied to the barrel.

 

The URX 4 is currently available for 5.56 rifles in 8.5”, 10”, 13”, and 14.5” lengths, and is equipped with Knight’s unique IBN mounting configuration. The idea was to create a more modular, and thus more serviceable, rail system that still maintains its strength and stiffness. Th IBN system torques the rail onto the weapon and allows the rail to act as the barrel nut. This design was developed to increase stabilization and provide a simpler solution that requires less specialized tools to install and maintain. A full array of modular accessories, iron sights, and panel kits utilizing the Keymod mounting brackets have been developed specifically to accompany this rail system. With the introduction of the URX 4, Knight’s Armament Co. demonstrates its continuing determination to intelligently design effective products.
