United States Navy Mark 11 Mod 0 Sniper Weapon System

The United States Navy Mk11 Mod0 Sniper Weapon System (National Stock Number 1005-01-475-7980) is a complete rifle system based around the highly accurate Knight's Armament Company SR-25 semiautomatic rifle. It was originally conceived and constructed to meet a requirement placed by the United States Navy SEALs.

General information

The Mk11 Mod0 (pronounced "mark eleven, mod zero") has received worldwide recognition as one of the most accurate and durable semiautomatic rifle systems in existence. It is currently in service with most operational components of United States Special Operations Command and also with the Israeli Special Forces. The system has also recently become available to civilian consumers at a unit price of around $7,500 USD not including extra firearm licensing fees, and obviously lacks the sound suppressor unit.

The Mk11 Mod0 system uses match grade 7.62x51mm NATO ammunition (similar to .308 Winchester). The Mk11 system includes the rifle, 20 round box magazines, QD scope rings, Leupold Vari-X Mil-dot riflescope, Versapod bipod, and QD sound suppressor, which is also manufactured by Knight's Armament Co. Flip-up BUIS (Back up iron sights) are attached to the modified gas block and upper receiver.

According to Knight's Armament Company, the heart of the Mk11 system is the free-floated RAS (Rail Accessory System) fore-end. The aluminum fore-end makes no contact with the barrel forward of the receiver, allowing for extreme accuracy. The Mk11Mod0 uses the KAC 11.35" long match RAS fore-end, which allows for quick attachment/detachment of MilSTD M1913 components.

The civian versions are guaranteed to produce sub-MOA groupings using factory match loads (under 1" at 100yds).

The Mk11 Mod0 is not capable of fully automatic fire; it is a semiautomatic rifle.

Note, the KAC SR-25 which is the basis of the Mk11Mod0 system is different from the U.S. Marine Corps M-25 Sniper Weapon System: though they both fire match grade 7.62x51mm NATO ammunition, the M25 is a modified, accurized M-14, while the KAC SR-25 is essentially a derivative of the AR-10, the predecessor to the AR-15 and M16 family of assault rifles.
