The FAB Defense GL-CORE S CQB Combat Stock (brand part no. FXGLCORES) was developed for one of the top Israeli counter-terrorism units as a primary buttstock, built to stay short and compact for close-quarters work while still holding up for mid-range engagements. Starting from the original GL-CORE buttstock, FAB Defense reworked the design around real operator feedback, molding it from durable, lightweight fiberglass-reinforced polymer composite for the M4/AR-15 platform. Whether you’re running a duty gun or a home-defense carbine, this stock is built to disappear into your gear rather than snag on it.
