Enhance your rifle’s performance, comfort, and modularity with the FAB Defense GL-Shock PCP Buttstock (FXGLSHOCKPC) — a premium, recoil-absorbing stock system designed for AR-15, M16, and M4 platforms. Built from high-grade Mil-Spec polymer, the GL-Shock PCP combines precision adjustability, integrated dual Picatinny rails, and an ergonomic cheek rest to deliver unmatched shooting stability and customization for tactical operators, competitive shooters, and serious enthusiasts.
Advanced Recoil-Reduction System
The GL-Shock PCP features FAB Defense’s patented shock-absorbing mechanism, which dramatically reduces felt recoil without sacrificing accuracy or weapon balance. This internal spring-and-buffer system absorbs impact energy during each shot, resulting in smoother firing, improved control, and faster follow-up shots — ideal for long sessions, high-round-count training, or duty use.
Adjustable Cheek Rest for Perfect Eye Alignment
Equipped with a precision-adjustable cheek rest, the GL-Shock PCP allows shooters to maintain a consistent cheek weld and eye alignment when using optics or magnified scopes. This ensures optimal target acquisition, sight picture, and comfort, even when transitioning between various shooting positions or accessory setups.
Whether you’re running a low-profile red dot or a high-mounted scope, the cheek rest height can be fine-tuned for your perfect fit.
Dual Built-In Picatinny Rails
The GL-Shock PCP includes dual side-mounted Picatinny rails, providing convenient accessory mounting options for sling adapters, monopods, or additional gear. The integrated rails eliminate the need for extra adapters, streamlining your build and keeping weight distribution balanced.
This design makes the stock ideal for tactical and competition rifles requiring modular adaptability in real-time.
Mil-Spec Construction — Rugged Yet Lightweight
Constructed from military-grade reinforced polymer, the GL-Shock PCP is engineered to endure the harshest field conditions. Its robust build resists impact, temperature extremes, and abrasion while maintaining a lightweight profile for improved maneuverability.
The black matte finish offers a professional, low-reflective appearance suitable for tactical environments while blending seamlessly with any AR-platform rifle.
Fully Adjustable and Operator-Focused
The stock’s six-position collapsible design allows precise length-of-pull adjustment to fit different shooter preferences, body types, or body armor setups. Combined with the adjustable cheek rest and recoil-reducing technology, this stock delivers complete control and comfort customization.
