The Knights Armament SR-25 ECR Enhanced Combat Rifle is a 7.62 NATO/.308 Win rifle featuring a 20” 5R cut rifled match grade alloy steel barrel with a 1:11 twist. The SR-25 ECC is based upon improvements ti a 20" duty system featuring an enlarged ejection port, a carbon cutter bolt carrier and a 7.62QDC flash suppressor. These allow for improved reliabilty when firing suppressed or in less than ideal environments. The QDC flash suppressor allows the family of 7.62 QDC suppressors to be easily added. Rifles includes the URX3.1 13.5" rail system with integrated 45 degree offset flip-up sights. The SR-25 series are semi-automatic rifle featuring the URX (upper receiver extending) free floating barrel system, an ambidextrous control system and a two-stage match trigger. The SR-25 ECR also comes with a retractable SOPMOD stock and one magazine.
Knight's Armament produces the SR-25, 7.62 caliber precision rifles from the solid foundation of the original 7.62 AR-10 rifle the Mr. Eugene Stoner developed in the 1950's. In 1989, Mr. Stoner joined with Knight's Armament and developed the SR-25 by combining his classic AR-10 and AR-15 platforms. KAC's current SR-25 features a free-floating barrel rifle system that, from the very beginning, was conceptualized as a precision target rifle. This platform is currently the primary firearm of thousands of military sniper units. KAC's Stoner rifles, such as the MK 11 and M110SASS series, has long been considered to be some of the most accurate and reliable semi-automatic 7.62mm rifles ever produced.
Knight's Armament has 21 years of experience in 7.62mm development, refinement, and service. The SR-25 was first conceptualized with its primary function being a sniper rifle. It delivers remarkable shooting accuracy with .5 MOA being attainable in a multiple target environment. The MK11 MOD0 and the M110 have embodied this experience and helped drive our company's renowned pursuit of perfection ultimately leading to the Enhanced Match Series of SR-25's.
The new Enhanced Match (E.M.) Rifle combines some of the best characteristics from the combat proven MK11 MOD0 and the M110 military rifles. The E.M. Rifle's Free-Floating barrel is a clone of the legendary MK11 MOD0's, but its Upper Receiver Extending (URX) forend with integral folding front sight was developed for the Army's XM-110 Rifle. The E.M. Rifle's ambidextrous magazine release was also a noteworthy XM-110 feature and the lightweight butt-stock is the same as the MK11 MOD0's. The SR-25 is widely used among the most elite special forces units around the world being first deployed and used by the US Navy Seals.
Unlike many of the AR-15's currently on the marker Knights Armament produces the majority of their parts in house. This ensures each part meets the KAC's quality standard and meets their own stringent benchmarks. Knights Armament utilizes the latest technology to ensure that each part manufactured conforms to the highest standards. KAC submits every product they manufacture to evaluations which scrutinize every aspect of the platform. Thousands of our nation's troops, law enforcement officers and everyday citizens experience the renowned reputation of these weapon systems and can attest to their quality. Knights Armament is regarded by many and producing the best complete rifles available to the commercial market.
Ball Mill Lightened Barrel:
Knight’s Armament has pioneered a unique and highly effective method for reducing weight and stress, while effectively dissipating heat in our barrels. Several of there weapon systems feature a Ball Mill Lightened, or Dimpled Barrel.This process reduces the overall weight of the barrel and effectively increases the surface area, allowing it to cool faster than a standard or fluted barrel.

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. (Read More)
Knight's 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. (Read More)
45 Degree Offset Sights:
The 45° Offset Rail Mounted Micro Folding Sights give a distinct advantage in target acquisition at various distances, as well as being a readily available back up in case an optic fails. These sights are the same make as our fully adjustable Micro Flip sights but are mounted onto a low-profile arm that fits the MILSTD 1913 rails and cants the sights 45°. These sights fold down into a low-profile configuration which, combined with the arm that rests in the recesses of the rails, provides an extremely lightweight and unobtrusive system. (Read More)
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. (Read More)
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.

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. (Read More)
Universal Rail Extending (URX):
