The M110 Semi Automatic Sniper System (M110 SASS) is an American semi-automatic sniper rifle that is chambered for the 7.62×51mm NATO round. It is manufactured by Knight's Armament Company, developed from the Knight's Armament Company SR-25, and adopted by the U.S. military following the 2005 US Army Semi-Automatic Sniper Rifle (XM110 SASR) competition.

The M110 is to be replaced by the lighter and more compact M110A1 CSASS, which is developed from the G28, a variant of the Heckler & Koch HK417; however, most M110A1 models fielded have been of the SDMR variant. In 2021, a newer variant, the M110A2, was showcased and seen in use in early 2022.
