The AS50 fifty caliber (12.7mm) sniper / antimateriel rifle is the latest development of the famous British company Accuracy International Ltd. First displayed in January 2005 in USA at the ShotShow-2005, this rifle reportedly has been developed especially for US SOCOM users, and is now being tested by the USNAVY Special Operations center. The AS50 is to provide combat operators with highly accurate and rapid aimed fire at extended ranges. To achieve such goal,the AS50 is built around gas operated, semiautomatic action, with "singlerear locking" (most probably, this mean a tilting bolt).

Easily detachable buttstock is fitted with recoil-reducing buttpad, as well as with folding rear grip, which also serves asa rear support leg. The folding quick-detachable bipod with adjustable legs is fitted as a standard. Top of the receiver is equipped with full length Picatinnytype rail which can accept any compatible scope mount; two additional rails are mounted on either side of the short handguard / barrel jacket. Rifle is fitted with four sling mounts, and can be brought down to basic sub-assemblies within three minutes for maintenance or compact transportation or storage.
