Knight's Armament M110

The M110 Semi-Automatic Sniper System was developed by Knight's Armament for the US Army as a 7.62x51 mm semi-automatic precision rifle. It was intended to replace or supplement bolt-action M24 sniper rifles where faster follow-up shots and suppressor integration were valuable.

The M110 is based on the AR-10/SR-25 pattern, using a gas-operated semi-automatic action, detachable magazines, rails, optical sighting systems, bipod, and sound suppressor. Its role is precision fire with faster engagement tempo than bolt-action rifles, not machine-gun volume.

In US service, the M110 supported snipers, spotters, and designated marksmen in Iraq, Afghanistan, and later deployments. It helped normalize semi-automatic precision rifles for military sniper teams, while later compact and improved variants addressed weight and handling concerns.
