Manufactured by <strong>Knight&#8217;s Armament Company (KAC)<\/strong>, it meets specific US Army specifications for a system that is faster, more modular and just as accurate as a traditional bolt-action rifle. <\/p><p>Since its introduction in 2008, the M110 SASS has proved its worth in many modern conflicts, combining the power of a sniper rifle with the speed of a semi-automatic system.<\/p><h2>Development and context<\/h2><p>In the early 2000s, US military operations in Iraq and Afghanistan revealed the limitations of bolt-action rifles in certain combat situations. The need for a semi-automatic precision firing system, capable of chaining several rapid shots together without compromising accuracy, became obvious. <\/p><p>In 2005, following a call for tenders issued by the US Army, the contract was awarded to <strong>Knight&#8217;s Armament Company<\/strong> for its model based on the SR-25 platform, a rifle derived from the AR-10. The M110 was officially adopted in 2008, and rapidly entered service with infantry, special units and intelligence forces. <\/p><h2>Technical specifications<\/h2><table><thead><tr><th>Features<\/th><th>Detail<\/th><\/tr><\/thead><tbody><tr><td>Caliber<\/td><td>7.62\u00d751 mm NATO (.308 Win) <\/td><\/tr><tr><td>Capacity<\/td><td>10 or 20 shots (detachable magazine)<\/td><\/tr><tr><td>Overall length<\/td><td>1,019 mm<\/td><\/tr><tr><td>Barrel length<\/td><td>508 mm (20 inches)<\/td><\/tr><tr><td>Mechanism<\/td><td>Semi-automatic, direct impingement<\/td><\/tr><tr><td>Weight (without optics)<\/td><td>Approx. 6.5 kg<\/td><\/tr><tr><td>Barrel thread<\/td><td>Yes (for silencer or hider flash)<\/td><\/tr><tr><td>Accessories<\/td><td>Bezel, bipod, Picatinny rail<\/td><\/tr><tr><td>Effective range<\/td><td>800-1 000 m<\/td><\/tr><\/tbody><\/table><h2>Design and ergonomics<\/h2><p>The M110 adopts a <strong>modular architecture<\/strong> based on the AR-10\/SR-25 platform.

Used by regular army snipers. <\/p><h3>M110 with silencer (SASS Suppressed)<\/h3><p>Many units use the M110 with a <strong>sound moderator<\/strong> (supplied by KAC), which reduces the sound and heat signature. Ideal for stealth missions. <\/p><h3>M110A1<\/h3><p>New generation of the SASS, adopted by the US Army from 2016. Manufactured by Heckler &amp; Koch, this version is based on the G28\/HK417 rifle, which is shorter, lighter and more maneuverable than the original M110. <\/p><h3>SR-25 (civil and military)<\/h3><p>Although distinct, the SR-25 is considered the forerunner of the M110, and is still used by many special forces and available on the civilian market in a variety of configurations. <\/p><h2>Comparison with other precision rifles<\/h2><table><thead><tr><th>Model<\/th><th>Caliber<\/th><th>Mechanism<\/th><\/tr><\/thead><tbody><tr><td>M110 SASS<\/td><td>7.62\u00d751 mm NATO<\/td><td>Semi-automatic<\/td><\/tr><tr><td>M24 SWS<\/td><td>7.62\u00d751 mm NATO<\/td><td>Lock<\/td><\/tr><tr><td>HK417 (G28)<\/td><td>7.62\u00d751 mm NATO<\/td><td>Semi-automatic<\/td><\/tr><\/tbody><\/table><p>The M110 distinguishes itself from the M24 by its ability to shoot quickly without compromising accuracy. Compared with the G28 (M110A1), it remains longer and heavier, but offers excellent stability for long-distance shooting. <\/p><h2>Military use<\/h2><p>M110 is used in :<\/p><ul><li><p><strong>U.S. Army<\/strong> (infantry, reconnaissance, special forces)<\/p><\/li><li><p><strong>Marine Corps<\/strong> (gradually replacing the M39 EMR)<\/p><\/li><li><p><strong>Special forces<\/strong> (often in silent version)<\/p><\/li><li><p><strong>Some of NATO&#8217;s allied armies<\/strong> have adopted it in small quantities.<\/p><\/li><\/ul><p>It is frequently used with a <strong>Leupold or Nightforce precision scope<\/strong>, a <strong>Harris bipod<\/strong> and sometimes <strong>secondary optics<\/strong> (red dot sights).<\/p><h2>Performance and reliability<\/h2><p>The M110 is renowned for its consistent accuracy (less than 1 MOA with match ammunition), mechanical reliability in harsh environments (sand, dust, humidity), and ease of maintenance for soldiers in the field. Its direct gas mechanism, although more demanding to clean, is optimized for NATO ammunition. <\/p><h2>Conclusion<\/h2><p>The <strong>M110 SASS<\/strong> embodies a new era in military precision shooting. It combines the power of the 7.62 mm caliber with the responsiveness of a semi-automatic rifle, while retaining formidable accuracy. Replacing the M24 in many corps, it has inspired a new generation of hybrid weapons, at the crossroads between sniper rifle and assault weapon.  <\/p><p>Even today, the M110 remains a <strong>benchmark in modern warfare<\/strong>, appreciated for its flexibility, range and effectiveness in both war zones and special missions.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"featured_media":3380,"template":"elementor_theme","meta":{"_acf_changed":false},"class_list":["post-3456","wiki","type-wiki","status-publish","has-post-thumbnail","hentry"],"acf":[],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 4.9.8 -
