Upgrade your Mossberg pump shotgun with the TRINITY Saddle Mount Picatinny Rail System, designed for Mossberg 500 and Maverick 88 12-Gauge pump shotguns. This precision-machined saddle mount provides a secure and stable platform for mounting optics, red dot sights, scopes, lights, or lasers, enhancing your shotgun’s versatility for hunting, tactical applications, range shooting, or home defense.

The solid one-piece saddle design straddles both sides of the receiver for superior stability under recoil while maintaining proper alignment for optics. The full-length 5.75-inch Picatinny top rail with 13 slots allows flexible placement of scopes and red dot sights to achieve the ideal eye relief and shooting position.

This mount also includes a removable 3.5-inch side Picatinny rail, perfect for attaching tactical accessories such as flashlights, lasers, or sling mounts. Installation is simple and requires no gunsmithing—the mount installs directly into the existing receiver pin ports, making setup fast and straightforward.

Constructed from lightweight aircraft-grade aluminum with a durable anodized satin black finish, this rail system delivers rugged reliability without adding unnecessary weight.

Whether you're preparing your shotgun for slug shooting, turkey hunting, range training, or defensive use, the TRINITY saddle mount provides a dependable optics platform built for performance.
