FAB Defense GL-Core S AR15 Buttstock

Compact AR Combat Stock

The GL-CORE S is FAB Defense's short-bodied collapsible stock for AR-15 and M4-pattern rifles and carbines. The CQB in the name means close quarters battle, and the stock is built for it: a trimmed, skeletonized frame that keeps the rifle short and quick to shoulder in vehicles, hallways and tight positions. It suits shooters building a compact carbine or SBR, or anyone who wants a lighter, slimmer stock than the standard M4 type.

Features

• Compact CQB Profile — The short body and cut-down lower section reduce bulk at the back of the rifle without giving up a full shoulder contact surface.
• Collapsible Design — The stock slides along a carbine buffer tube, the round tube behind the receiver, so you can set length of pull to suit your build, body armor or shooting position.
• Ribbed Adjustment Lever — A textured lever under the front of the stock releases it to change positions and is easy to find with a gloved finger.
• Skeletonized Frame — Open sections through the lower frame remove material for less weight while the outer structure stays rigid.
• Smooth Cheek Weld Surface — The rounded, enclosed top gives your cheek a consistent resting point when you line up with your sights or optic.
• Textured Butt Plate — A ribbed rear surface helps the stock stay planted in the shoulder instead of sliding off under recoil or movement.
• QD Sling Socket — A quick-detach socket at the rear accepts push-button sling swivels, so a sling can be clipped on or off in a moment.
• Black Polymer Construction — The molded polymer body is black throughout and carries the FAB Defense logo on both sides.

Fit and Construction

The GL-CORE S mounts on an AR-15/M4-style carbine receiver extension and replaces the factory collapsible stock directly. FAB Defense molds the body as a single polymer shell with an enclosed upper section and an open lower frame, which keeps weight down and leaves the outline slim. Check your buffer tube type before ordering so the stock matches your rifle.
