Draft:SR-15

From Wikipedia, the free encyclopedia

The SR-15 is an semi-automatic rifle designed by Eugene Stoner and manufactured by Knight’s Armament Company.

The SR-15 uses a direct impingement gas system. It is loosely based on Stoner ArmaLite AR-15, with 5.56x45mm NATO caliber. Most parts of the SR-15 are interchangeable with the AR-15 and M16, except the upper and lower receivers. Inside a URX 4 M-LOK handguard, it floated easily. The E3 round-lug bolt design is being optimized to improve function and prolong bolt life exceeding industry standards.The drop-in two-stage trigger ensures surgical speed shooting at close range along with assisting with pinpoint marksmanship. The Knight brand of 5.56mm QDC Signature Reduction Devices is compatible with the 5.56mm 3-Prong Flash Eliminator, which significantly decreases flash signature by interfering with propellant gas ignition forward of the muzzle. It additionally does not vibrate when fired or impacted.[1]

History

[edit]

In May 2000, United States Special Operations Command took interest in the SR-25 and particularly its high magazine capacity and faster engagement time compared to bolt-action rifles. After some modifications, SOCOM adopted the SR-25 as the Mk 11 MOD 0. With the success of the SR-25, Knight's Armament started development of SR 25 in the AR-15 platform that has become SR 15 in 2007.[2]

Design

[edit]

The SR-15E3 IWS Mod 1 has been heavily improved on dual-spring extractor. In the AR-15, there are Extractor problems often due to centrifugal force from the bolt rotates. Wider at the back for the dual-spring, the "E3" extractor's additional material adds weight to help balance the extractor's front part and prevent it from backing away from the cartridge-case rim during rotation.[3]

The SR-15E3 IWS Mod 2 improved on a two-stage drop-in trigger that enables precise shooting is one of the upgraded features, along with an improved bolt-lug design that attempts to extend service life.[4]
