The Romanian PSL (Puşcă Semiautomată cu Lunetă) sniper rifle, also known as the FPK sniper rifle (stamped FPK on the receiver) was developed in the 1970s as the Romanian version of a designated marksman rifle, much like the American M21 system and Soviet SVD Dragunov. The PSL is built using an RPK stamped receiver with the AK long stroke piston, but chambered for 7.62x54mm R. The Romanians never really used the PSL as a sniper rifle in their armed forces, instead choosing other long range weapons (such as commercial bolt action rifles) for that task. The Romanian PSL sniper rifle is commonly encountered in the U.S. and is often sold as a Dragunov to the uninformed. In the United States, the PSL is also known under the names ascribed by U.S. distributors like ROMAfK-3 and PSL-54C (Century Imports), SSG-97 (as called by Interordnance) and the Romanian "Dragunov" or Romanian "FPK" (as sold by Tennessee Guns which are assembled in the U.S with Romanian parts).
