FAB Defense GL CORE S CP CQB Optimized Combat Stock Small and Compact Design Cheek Rest Included Fits Mil Spec And Commercial Tubes Black FX GLCORESCP UPC 7290111585890
Product Description
The F.A.B. Defense® GL-CORE S CP (SKU: FX-GLCORESCP / UPC: 7290111585890) is a purpose-built, CQB-optimized collapsible buttstock engineered in collaboration with elite Israeli counter-terrorism operators. Combining the ultra-compact GL-CORE S chassis with the integrated GCCP 3-position adjustable cheek rest, this stock delivers rapid weapon manipulation in confined environments while establishing a repeatable cheek weld for elevated red dots, holographic sights, and LPVO optics.
Injection-molded from high-density fiberglass-reinforced polymer composite, the GL-CORE S CP withstands heavy operational impacts, extreme temperature swings, and exposure to gun solvents without warping or cracking. To eliminate the distracting receiver extension wobble common on standard carbine stocks, F.A.B. Defense includes interchangeable internal polymer adapters that lock tightly onto both 1.148-inch Mil-Spec and 1.168-inch Commercial-Spec buffer tubes. Its snag-free exterior profile eliminates protruding latches, while the inversed adjustment lever prevents accidental length-of-pull collapse during dynamic movement.
At the rear, a flat-faced, non-slip rubberized buttpad provides positive shoulder purchase whether shooting slick or wearing tactical plate carriers and heavy chest rigs. Dual integrated rear Quick-Detach (QD) sling swivel sockets allow ambidextrous two-point or single-point sling mounting out of the box. The factory-installed GCCP cheek piece adjusts vertically across three positive locking positions, allowing shooters to dial in exact eye relief and optical centerline alignment.
*Armorer Bench Notes & Real-World Staging Guidance:*
Fitment Matrix: Compatible with AR-15, M4, AR-10, and AK/VZ chassis systems utilizing standard Mil-Spec (1.148" OD) or Commercial-Spec (1.168" OD) carbine receiver extensions. CRITICAL WARNING: Verify your buffer tube outer diameter before installation and install the matching internal polymer adapter shim—forcing a Mil-Spec shim onto a Commercial tube will bind the stock. Not compatible with A1/A2 fixed rifle tubes or pistol buffer tubes. Note that raising the GCCP cheek rest on AR-15 platforms may obstruct the charging handle when the stock is fully collapsed; set your length of pull prior to staging.
- Ensure the host firearm is completely clear, magazine removed, and chamber visually and physically verified empty before beginning installation.
- Remove any existing buttstock from the carbine receiver extension by pulling downward on its adjustment latch and sliding it off the rear of the tube.
- Select the appropriate internal polymer adapter shim for your buffer tube (Mil-Spec 1.148" or Commercial 1.168") and verify it is seated cleanly inside the GL-CORE S CP body.
- Depress the inversed positioning lever firmly to retract the locking pin, slide the stock onto the receiver extension to your desired length-of-pull detent, and release the lever.
- Pull sharply rearward on the stock to confirm full locking pin engagement, adjust the GCCP cheek rest to match your optic height, and cycle the charging handle to verify clearance.
