Upgrade your Mossberg platform with the TRINITY Saddle Mount Picatinny Rail Adapter with Shell Holder, engineered for enhanced functionality, durability, and quick-access performance. Designed for compatibility with Mossberg 500 and Maverick 88 12-gauge pump platforms, this system provides a stable optics mounting solution combined with convenient onboard ammunition storage.
The precision-machined saddle mount features a rugged one-piece design that securely straddles the receiver, delivering excellent stability under recoil. The full-length 5.75-inch Picatinny rail with 13 slots allows for flexible mounting of scopes, red dots, or other optics for improved accuracy and target acquisition.
Included is a removable 5-round shell holder, constructed from high-strength glass-filled polymer. This lightweight yet durable carrier attaches directly to Picatinny rails, keeping your ammunition easily accessible while securely retaining shells during movement and recoil.
Installation is fast and simple using existing receiver pin ports—no gunsmithing or permanent modifications required. Finished in a non-glare matte black anodized coating, this mount is built for long-lasting performance in demanding environments.
