Kel-Tec R50BLK R505.7x28mm 50+1 16.10" Threaded Barrel, Black Receiver & Polymer Grip, Side-Folding Stock, Adjustable Sights, QD Sling Mount

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 x 28 threaded - 16 inch barrel. It 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. Theres a QD sling cup just above the magazine release for mounting a single point sling and the AR style charging handle offers smooth manipulation.
