Why the FAB Defense GLR-16 CP Is a Smart Upgrade
The GLR-16 CP blends practical ergonomics with thoughtful engineering: an adjustable cheek-rest lets you obtain a perfect cheek-to-stock interface for consistent sight alignment with optics and red dots, while the anti-rattle mechanism keeps the stock tight to the receiver for silent, zero-friendly performance. The result is faster target acquisition, reduced shifting under recoil, and a more comfortable shooting experience over long strings of fire.
Core Features & Benefits
Adjustable Cheek-Rest: Fine-tune your cheekweld height to match optics, magnified scopes, or red-dot sights for repeatable eye-to-optic placement and improved accuracy.
Anti-Rattle Mechanism: Built-in retention reduces play between stock and buffer tube to minimize noise and movement—critical for tactical and hunting applications.
Robust Polymer Construction: High-impact, reinforced polymer provides exceptional durability while keeping weight low for maneuverability.
Ergonomic Profile: Contoured buttpad and streamlined geometry improve shoulder interface and control during transitions and follow-up shots.
Designed for AR Platforms: Engineered to fit AR-15 / M16 / M4 platforms, making it a direct, user-friendly upgrade for most modern carbines (verify compatibility with your receiver and buffer tube spec prior to purchase).
Sleek Black Finish: Low-glare black surface integrates cleanly with tactical builds and accessory systems.
Performance You Can Feel
Whether you’re dialing in a precision optic or running fast on the move, the GLR-16 CP’s adjustable cheek-rest brings your eye to the same spot shot after shot. The anti-rattle system dramatically improves the feel of the rifle by eliminating stock wobble and the associated audible clicks that can give away position. Lightweight yet stout, this stock improves rifle balance without adding unnecessary bulk.
Compatibility & Installation
Platform: AR-15 / M16 / M4 family (check buffer tube spec before installation).
Installation: Simple drop-on replacement for compatible buffer tubes; installs with basic tools in minutes. Always confirm fit and function before live-fire.
(If in doubt about buffer tube spec or compatibility, consult your rifle manual or a qualified gunsmith.)
