FAB Defense M4 Sliding Stock Mossberg 500

This FAB Defense M4-style stock system is designed to transform your Mossberg shotgun into a modern sporting platform. It replaces the standard fixed stock with an ergonomic pistol grip and a 6-position collapsible buttstock, significantly improving muzzle control, firearm versatility, and storage capacity for hunting, sport shooting, and outdoor use.

• Enhanced Ergonomics & Control: The rock-solid, one-piece ergonomic design includes an integrated pistol grip with a non-slip texture. This setup encourages a more natural shooting posture, improves finger-to-trigger contact, and provides better muzzle control during quick shots. The stock is slightly angled to help counter muzzle rise and redirect recoil more linearly into the shoulder.
• 6-Position Adjustability: The M4-style telescopic buttstock allows you to adjust the length of pull (LOP) to six different positions. This is essential for tailoring the shotgun to different body sizes, thick winter clothing, or protective gear, and makes the firearm easier to store or transport in tight spaces.
• Advanced Features & Storage: Constructed from durable, lightweight reinforced polymer composite, the stock includes a watertight storage compartment in the pistol grip for batteries or a compact cleaning kit. It also features preset ambidextrous holes for SLS Quick Release Sling Swivels, allowing for multiple carry configurations.
• Recoil Mitigation: The stock design and angled grip work together to reduce felt recoil and muzzle flip, allowing for faster follow-up shots.
• Easy Installation: A straightforward "drop-in" installation that replaces the factory stock without needing professional tools or permanent modifications.
