FAB Defense GL-Core Adjustable Cheek Rest - Flat Dark Earth Synthetic for AR-Platform$85.30
Availability: In Stock
The FAB Defense GL-Core adjustable cheek rest brings ergonomic precision to your AR-platform rifle. Built around an integrated cheek weld and rubberized buttpad, this matte black synthetic stock combines comfort with functionality—essential whether you're dialing in at the range, hunting from a bench, or running drills. The GL-Core's compact profile and thoughtful design keep your shooting setup clean and snag-free, so nothing catches on gear or webbing when you need to move.
Fit is rarely one-size-fits-all, and FAB Defense knows it. The GL-Core ships with interchangeable buffer tube adapters engineered to lock tight on both Mil-Spec and Commercial buffer tubes—no wobble, no guesswork. The adjustable three-position cheek rest lets you dial in the right height for your optic setup and natural shooting posture, which translates directly to faster target acquisition and more consistent shooting positions across different configurations.
Construction is lightweight yet durable: fiberglass-reinforced polymer composite that won't add unnecessary weight to your rifle. The integrated rear sling swivel connectors give you solid attachment points, and the inversion-designed positioning lever won't pop open during normal handling or movement. For AR shooters who want a stock that fits well, stays put, and adapts to different optics and shooting styles, the GL-Core delivers straightforward, no-nonsense performance.
