The Fab Defense GL-CORE CP Buttstock with Adjustable Cheek-Rest for Milspec and Commercial Tubes Black is a compact, lightweight upgrade for AR-15 and M4 style rifles. Built from fiberglass reinforced polymer composite, it combines an integrated cheek weld, ergonomic rubberized butt-pad, and interchangeable tube adapters to deliver a secure, rattle-free fit on both Mil-Spec and Commercial buffer tubes. The CP configuration adds a height-adjustable cheek rest that supports consistent eye alignment with modern optics and holographic sights.

This buttstock is well suited for range use, training, and general-purpose rifle builds where comfort and repeatable cheek weld are important. The sleek profile minimizes snag points while still offering multiple sling attachment options, making it a practical choice for shooters who move frequently between positions. With thoughtful ergonomics and durable construction, Fab Defense continues its reputation for functional, shooter-focused rifle accessories.
