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. This carbine features a side-folding stock that rests nicely on either side of the grip when folded and a 1/2 x 28 threaded - 16 inch barrel. This KelTec does come with some utility sights that are adjustable for windage and elevation, however the R50 receiver offers over 7 inches of picatinny rail space up top for mounting just about any optic or accessory you like. 2 inches of rail space on the bottom is ideal for light and grip options. There's a QD sling cup just above the magazine release for mounting a single point sling and the AR style charging handle offers smooth manipulation.
