FAB Defense GL-Core S CP CQB AR-15/M4 Buttstock w/Adjustable Cheek Rest - Black

The FAB Defense GL-Core S CP is a CQB-optimized collapsible buttstock purpose-built for AR-15 and M4-pattern carbines. Originally developed for Israeli counter-terrorism units as a primary combat stock, the GL-Core S CP brings that mission-focused design to the commercial AR platform, integrating an adjustable cheek-rest for a consistent, optic-friendly cheek weld during dynamic engagements.

The stock body is molded from black fiberglass-reinforced polymer, giving the GL-Core S CP a lightweight yet rugged build that shrugs off recoil and field abuse. An integrated adjustable cheek-rest lets the shooter dial in height for use with red dots, low-power variable optics, or traditional iron sights, while the CQB profile keeps the package compact for fast shoulder transitions and a tight cheek weld behind the optic.

Designed to mount directly to a standard Mil-Spec buffer tube (tube not included), the GL-Core S CP bolts up to AR-15 and M4 lower receivers and provides a clean drop-in upgrade. The black finish sits naturally on most rifle builds, delivering an Israeli-spec CQB buttstock to any AR-platform shooter.
