The FAB Defense GL-Core CP adjustable cheekrest buttstock brings ergonomic rifle control and optics-friendly versatility to your AR-platform build. This OD Green synthetic stock combines a shaped rubber buttpad with an adjustable cheek rest, making it easier to find a consistent and comfortable sight picture whether you're running a red dot, holographic sight, or magnified optic. The modular design works on both Mil-Spec and commercial buffer tubes, so it adapts to your existing receiver without hassle.
What sets the GL-Core CP apart is its attention to practical shooting geometry. The integrated cheek weld supports natural head positioning for quick target acquisition, while the adjustable cheek rest lets you dial in the exact height you need for your scope or sight setup. The rubberized buttpad grips your shoulder and resists slipping during recoil, and the compact, snag-free design won't catch on tactical gear or sling webbing during transitions. Two integrated QD sling attachment points give you flexible carry options without adding bulk.
Built from fiberglass-reinforced polymer composite, the GL-Core CP is light enough that it won't tax your rifle's balance yet durable enough to handle hard use. The interchangeable tube adapters ensure a tight, rattle-free fit, and the inset positioning lever resists accidental deployment. This is the kind of thoughtful hardware that separates a rifle you tolerate from one you actually enjoy shooting.

Yes. The GL-Core CP comes with interchangeable adapters that fit both Mil-Spec and commercial buffer tubes, the two standard sizes used on modern AR-platforms. Just verify which tube you have and use the correct adapter for a tight, rattle-free fit.
Absolutely. The three-position adjustable cheek rest is specifically designed to accommodate different optics heights, so you can dial in the exact cheek position you need for natural head placement and consistent eye relief whether you're running a low-mounted red dot, holographic sight, or higher magnified scope.
The GL-Core CP has two integrated QD (quick-detach) sling swivel attachment points at the rear, so you can run a single-point sling, two-point sling, or whatever configuration suits your shooting style.
The cheek rest offers three discrete positions to raise or lower cheek contact. The adjustment lever is inset so it won't catch on gear and won't deploy accidentally during handling or recoil.
