This carbine features a side-folding stock that rests nicely on either side of the grip when folded and a  x 28 threaded &#8211; 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.
