KelTec R50 is the right carbine for you. This side-folding tack driver gives you maximum speed, accuracy and power downrange with its 16 inch, threaded barrel and optic mounting option. Like many KelTecs, the Kel-Tec R50 is ideal for small game hunting, bullseye shooting or just showing off for your friends at the range. R50 stands for Rifle - 50 Rounds in complementing contrast to the P50, the pistol version of the same platform.
