Kel-Tec PLR-16

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 barrel, the 5.56×45mm bullet's velocity is slightly reduced compared to its velocity from a traditionally 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 an M-1913-style Picatinny rail molded to the top of the receiver to accept various optical sights.
