FAB Defense GL-CORE S CQB Combat Stock for AR-15/M4

Description

The FAB Defense GL-CORE S was developed as a short, rugged buttstock optimized for close-quarters battle (CQB) while retaining stability for mid-range engagements. The design originated from the GL-CORE and incorporates user-requested changes to reduce profile and improve handling in tight environments. It features an integrated cheek weld tuned for M4/AR-15 platforms and interchangeable buffer tube adapters for both Mil-Spec and Commercial tubes. Construction uses a durable composite identified by the manufacturer as fiberglass reinforced polymer.
