The Newest Long -range Precision Rifle of the U.S. Military
The M110A1 is an American military semi-automatic precision rifle that is chambered for the 7.62×51mm NATO round. It is manufactured by H&K and developed from HK417; the HK417 is a gas piston variant of the AR-10 platform, with the short-stroke gas piston derived from the H&K G36. Compared to the G28, the M110A1 uses an aluminum upper receiver instead of steel to meet weight requirements, and is similar to the Germany Bundeswehr G28 configuration.
