The PLR-16 is a gas operated, semi-automatic pistol chambered in .223 Remington (5.56mm NATO) caliber. It is intended to be the ideal Silhouette shooting and hunting pistol. The PLR-16 has a conventional, long-stroke gas-piston operation and utilizes the proven Johnson/Stoner breech locking system. The rear sight is adjustable for windage. The front sight is similar to an AR-15 style rifle, and adjustable for elevation. An integrated MIL-STD-1913 Picatinny rail will accept a multitude of standard accessories. The muzzle is threaded to accept standard attachments such as a muzzle brake or flash hider. Except for the barrel, bolt, sights, and firing mechanism, the PLR-16 pistol is made entirely of high-impact glass fiber reinforced polymer.
