M k.11 Mod 0 sniper rifle

In the late 1990s, an improved version based on the KAC SR-25 was submitted to the U.S. Navy SEALs for testing and evaluation. Based on the evaluation results, the SEALs submitted a request for design changes. Later, the U.S. Special Operations Command officially adopted the improved SR25 and supporting accessories, and officially named it Mk . 11 Mod 0 sniper weapon system (NSN 1005-01-475-7980) in accordance with Navy nomenclature. . The M k. 11 Mod 0 system uses match-grade 7.62×51mm NATO standard ammunition (.308 Winchester) and can only fire semi-automatically. The entire Mk . 11 system includes 1 rifle, 10 KAC standard 20-round box magazines, QD scope ring, Leupold Vari-X 3.5-10 x mil dot sight, mounted on the KAC tripod mount Harris bipod, and a QD type silencer, as well as KAC folding BUIS (abbreviation for Back up iron sights) installed on the improved gas hoop and upper receiver. The M k. 11 system uses KAC's 11.35-inch (288mm) match-style RAS long handguard. This free-floating aluminum handguard does not come into contact with the barrel and maintains barrel accuracy.

The U.S. Navy Special Forces purchased 370 sets of the Mk . 11 Mod 0 system. In addition to being adopted by the Naval Special Forces, the 75th Ranger Regiment was also equipped with Mk . 11 Mod 0. The Israeli Special Forces also began to use it. The system is now also Sold to American civilians, the unit price is about US$7,500, but does not include a silencer. While AWB94 is still in effect, the civilian version can only be sold with 5-round and 10-round magazines. Since AWB94 automatically expired in 2004, in areas that have been opened Can be sold with 20-round box magazine. The military version has a 20-inch lightweight match barrel, while the civilian version has a 24-inch barrel.

In the acceptance work that the SEAL team has completed, the acceptance test is divided into three stages. In the first phase of testing, each tested rifle fired four groups of five rounds at the same paper target at a distance of 100 meters. The dispersion of the projectiles of two groups must be within 25mm (1MOA), and the dispersion of the projectiles of the remaining two groups must be within 38mm. The second stage is to install four groups of five rounds after adding a silencer. The test results are that the dispersion of the projectiles of two groups must be within 38mm, and the dispersion of the other two groups of projectiles must be within 50mm. In this stage of the test , after each gun passes the inspection, the silencer used will be engraved with the same serial number as the rifle as its dedicated silencer. In the first two stages, the M118LR sniper bullet equipped by the navy is used. When fired from a 510mm barrel, the muzzle velocity is 784m/s. The third stage of the test is a reliability test. Each gun must fire 200 rounds without any malfunction. Since the number of M118LR bullets is limited (and relatively expensive), M80 ordinary bullets are used in this stage of the test. The distance is also relatively close.

The dispersion of factory-assembled match bullets for civilian use can also be less than 1 inch at 100 yards (it is said that it can reach 0.3MOA in actual tests).

The M110 SASS later tested and equipped by the U.S. Army was similar to the Mk . 11 Mod 0 system, except that the M110 used a newer URX rail system, a fixed stock with adjustable length, and a flash hider installed in front of the barrel. However, it is said that the Delta Commandos and Green Berets believe that the M110 is not as good as the Mk11 MOD , so the Army Special Forces still retains a large number of Mk11 MOD .
