The M0A1 is the USMC's Scout Sniper Rifle. Based on the Remington 700's action the rifle is hand assembled by the Corp's highly trained expert armorers. It is equiped with an Unertl 10x scope specially contracted by the Marines. The rifle maintains one minute of angle(MOA), in other words it holds a one inch group at 100 yards, 2 inch group at 200 yards, etc... In the hands of an experienced marksman it is accurate up to 1000yards (915meters)

The weapon widely regarded as the "Ultimate Sniper Rifle". Basically, it's a modified Remington 700 rifle. Introduced late in the Vietnam War.
