The M110 Semi-Automatic Sniper System is a semi-automatic rifle that uses the 7.62×51mm NATO round, developed by the American firearm manufacturer Knight’s Armament Company.

The M110 Semi-Automatic Sniper System is intended to replace the M24 Sniper Weapon System used by snipers, spotters, designated marksman, or squad advanced marksmen in the U.S. Military. However, the Army still plans on acquiring M24s from Remington until February 2010. The U.S. Military ran a competition involving several designs, including rifles from Knight’s Armament Company, Remington, and DPMS Panther Arms.

In April 2007, U.S. Military soldiers from Task Force Fury in the Afghanistan theatre were the first in a combat zone to receive the M110. The troops rated the weapon extremely highly, noting the quality of the weapon and its semi-automatic capabilities compared to the bolt-action M24.

The rifle has ambidextrous features such as a double-sided magazine release, safety selector switch, and bolt catch.
The rifle is similar to the SR-25/Mk 11 Mod 0 semi-automatic precision rifles, but differs significantly in buttstock and rail system design. The SR-25, Mk 11 Mod 0, and M110 are based loosely off the original AR-10 developed by Eugene Stoner but feature additional refinements instituted by KAC to maximise parts commonality with the AR15 / M16, improve weapon reliability, and increase accuracy.

The main differences between the Mk 11 Mod 0 and M110 are:

The rail system used: the KAC Free Floated RAS on the Mk 11 is replaced by a URX modular rail system with integral folding front 600 meter back-up iron sight (BUIS).

The M110 buttstock is fixed, although the buttplate is adjustable for length of pull to match user preferences. Adjustment can be made without tools via a notched hand-tightened knob on the right-hand side of the stock. The fixed buttstock also features integral quick-detachable sling swivel sockets located on each side of the stock near the rear of the lower receiver.

The addition of a flash hider to the barrel of the M110, which also necessitates a modified QD Suppressor unit similar to that on the Mk 11 Mod 0.

The M110’s use of KAC’s one-piece 30 mm scope mount instead of two separate scope rings.

Other changes were made when the XM110 made the transition to the M110. Features added were a buttstock hand-tightening knob, sling swivel sockets, a double sided bolt catch, and a button on the folding front sight to allow it to be locked into position.
