The AW50 is a .50 BMG anti-materiel rifle designed by Accuracy International. It is a re-engineered version of the Accuracy International Arctic Warfare L96 sniper rifle (the standard issue sniper rifle in the British military).


The AW50 is intended to engage a variety of targets including radar installations, light vehicles (including light armoured vehicles), field fortifications, boats and ammunition dumps. The standard ammunition combines a penetrator, high explosive and incendiary effect in a single round.

The weight of the weapon (15 kg), combined with a muzzle brake and a hydraulic buffer system in the butt, gives the AW50F relatively low recoil and enhances accuracy.

The MIL STD 1913 sight rail can hold a variety of equipment; the normal sight for the AW50 is the Schmidt & Bender 3-12x50 PM II with Al Mil Dot reticle, 0.2 MRad clicks and elevation to 1500 m and laser protection. Night vision device sights such as the Simrad KN series or Hensoldt NSV 80 can also be fitted.


The AW50F is a folding stock variant which fires the multi-purpose Raufoss Mk 211 cartridge and other rounds. Most of the rifle is made in the United Kingdom; The barrels are sourced from three different manufacturers: Loather Walther, Boarder and Maddco. The weapon's stock folds for portability. It has a fully adjustable bipod and buttstock heel rest. Four sling loops allow shoulder and hand carrying of the rifle.[3]

Weighing 15 kilograms, the AW50F rifle is approximately four times the weight of a typical assault rifle. The NM140 .50 calibre ammunition is also heavy. The weight of the weapon, combined with a muzzle brake on the front end and a hydraulic buffer system in the butt, gives the AW50F a relatively low recoil and enhances accuracy.
