FAB Defense GL-Core S CP Adjustable Cheekrest Buttstock for AR-Platform, Matte Black Synthetic$85.30
Availability: In Stock
The FAB Defense GL-Core matte black synthetic buttstock for AR-platform rifles gives you a comfortable, secure cheek weld and shoulder pocket without the bulk or weight of traditional fixed stocks. Built from fiberglass-reinforced polymer, it's engineered for shooters who want ergonomic control and fast target acquisition whether you're running drills at the range, hunting, or training with your modern sporting rifle. The GL-Core uses interchangeable buffer tube adapters, so it works with both Mil-Spec and commercial tubes—no guessing, no gaps.
The integrated cheek rest is built into the rubberized buttpad, giving you a natural anchor point for consistent sight picture without adding bulk to your setup. The compact design keeps things streamlined; there are no protruding edges to snag on your gear, sling, or tactical kit during movement or transitions. The inverted positioning lever stays put—no accidental opens when you're shouldering or moving through rough country. A pair of integrated quick-detach sling swivel connectors gives you flexibility for how you run your sling, whether that's a single-point, two-point, or none at all.
At its core, the GL-Core is about getting a stock that fits your tube first try and feels good when you shoot. Light weight, durable, and purpose-built for the shooter who doesn't want to fuss with adapters or worry about a loose fit degrading their rifle's handling.
