WASR-10

The Wassenaar Arrangement Semi-automatic Rifles (more commonly referred to as the WASR-series rifles) are manufactured in Romania by the long established Cugir Arms Factory as result of a collaboration between Century International Arms and Cugir. According to Century Arms, an American company who imports and modifies the WASR, they are semi-automatic only, single stack variants generally based on the Romanian Model 63, Pistol Mitralieră model 1963/1965 (PM md. 63), and GP 75 AKM rifles Avtomat Kalashnikova Modernizirovanniy (AKM) series of Kalashnikov rifles originally manufactured in Russia. Century decided to import the WASR to meet U.S. demand for AK style firearms. U.S. federal code 18 USC 922R stipulates that 10 major components of a firearm categorized by federal law as a “semi-automatic assault weapon” had to be manufactured in the U.S. The WASR-series rifles take their name from the 1996 Wassenaar Arrangement, a multilateral export control regime (MECR), the purpose of which is to monitor and limit the proliferation of certain conventional weapons and dual-use technologies.

The WASR-series rifles use a Romanian-made receiver, but lack the dimple (used to center the magazine) above the magazine well seen in the other AK series of rifles. Instead WASR's use internally welded spacer plates to center the magazine. The arrangements of the rivets on the receiver and front and rear trunnions are also different than many other AK derivatives. There are no known clones of the WASR series to date. The lack of dimple and rivet layout allow for positive ID in the many different stock configurations.

WASR-series rifles are manufactured with stamped sheet metal receivers that were originally intended for single-stack magazines. Featuring hard chrome-lined barrels, side-mount scope rail and wooden , WASR-series rifles are commonly imported to the United States by Century International Arms.
