The Kel-Tec PLR-16 is a gas-operated, semi-automatic pistol version of the SU-16, chambered in 5.56 NATO, manufactured by Kel-Tec Industries of Florida. The PLR (Pistol, Long Range) was designed for recreational target shooting, and small game, varmint, or predator hunting. Due to the PLR's 9.25 in barrel, the 5.56×45mm bullet's velocity is slightly reduced compared to its velocity from a traditionally 20 in barrel. The PLR-16 combines the multi-lug rotating bolt design and breech-locking system of the AR-15 with a gas piston system. The pistol accepts the same STANAG magazine that is used in the M-16, AR-15, and other NATO rifles chambered for 5.56×45mm. The PLR-16's frame is constructed of reinforced polymer, making the pistol both durable and light-weight. The frame incorporates a Picatinny rail molded to the top of the receiver to accept various optical sights.
