The
United States Navy Mk 11 Mod 0 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
U.S. Navy SEALs.
The Mk 11 Mod 0 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; however, it lacks the sound suppressor unit.
The Mk 11 Mod 0 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, Harris swivel-base bipod on a Knight's mount, 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.
Issued with 20-round box magazines, the civilian version is also available with
assault weapons ban friendly 5-round and 10-round magazines. The barrel used is a 20 in (508 mm) lightweight match barrel, though civilian match barrel of 24 in (610 mm) inches exist.
According to Knight's Armament Company, the heart of the Mk 11 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 Mk 11 Mod 0 uses the KAC 11.35 in (288 mm) long match RAS fore-end, which allows for quick attachment/detachment of MIL-STD-1913 components.
The civilian versions are guaranteed to produce groupings using factory match loads of less than 1 inch at 100 yards (28 mm at 100 m) or 0.3
angular mil.
The Mk 11 Mod 0 System is very similar to the KAC
XM110 SASS Semi-Automatic Sniper System, though the XM110 utilizes the newer URX Rail system, a length-adjustable fixed buttstock, and an integrated flash hider.
The Mk 11 Mod 0 is not capable of fully automatic fire; it is a
semiautomatic rifle.
Note, the KAC SR-25 which is the basis of the Mk 11 Mod 0 system is different from the
M25 Sniper Rifle used for a time by USSOCOM. Although they both fire match grade 7.62 x 51 mm NATO ammunition, the M25 is a modified, accurized
M14, 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.
