The GL-Core S was specifically designed for one of the best Israeli Counter-Terrorism units, to be used as a primary buttstock. It is short and compact for CQB scenarios but will still provide strength and stability for mid-range engagements. It features an integrated cheek weld, non-slip slim buttpad and an interchanging buffer tube adapter that allows it to fit on either Mil-Spec and Commercial buffer tubes. Comes with two integrated QD sling swivel sockets. The CP version includes an additional adjustable cheek rest, designed to support the use of different optics and holographic sights on the AK and VZ 58 platforms.
