The M110 Semi-Automatic Sniper System is the US Army's standard semi-automatic sniper rifle, built on an AR-10/SR-25 platform by Knight's Armament Company. The 20-inch match-grade free-floated barrel, URX rail system, and folding back-up sights deliver sub-MOA accuracy. The integral suppressor option (KAC Quick-Detach) allows quiet operations. It replaced the bolt-action M24 in many Army units requiring faster follow-up shots.
