The FAB Defense GL-Core S CP CQB Combat Buttstock (brand part number FX-GLCORESCP) traces its design directly back to one of the top Israeli counter-terrorism units, which asked for a stock short and compact enough for close-quarters work without giving up the strength needed for mid-range engagements. FAB Defense molds the stock from black fiberglass-reinforced polymer for a rifle that stays light without feeling flimsy, and builds in an adjustable cheek rest so shooters running a taller optic or magnified scope can get a proper cheek weld every time. Interchangeable buffer tube adapters let the stock lock down tight on both Mil-Spec and Commercial diameter tubes, so it drops onto most AR-15/M4 builds without hunting for a specific tube spec. It’s a purpose-built option for shooters who move through doorways and tight spaces as often as they do open range.
