Upgrade your shotgun with the TRINITY Saddle Mount and Shell Holder Combo compatible with Mossberg 590 12 Gauge, designed to enhance versatility, improve targeting capability, and provide quick access to extra ammunition.
This complete combo includes a precision saddle mount with a full-length Picatinny rail and a removable 5-shell holder, giving you both optics mounting capability and convenient on-board ammo storage.
The solid one-piece saddle mount design securely straddles both sides of the receiver, delivering maximum stability under recoil. Installation is quick and easy using the existing receiver pin ports—no gunsmithing or special tools required.
The 5.75-inch Picatinny rail with 13 slots allows for flexible mounting of scopes, red dots, or other optics while maintaining a secure and balanced setup.
The included polymer shell holder attaches directly to the rail and holds up to 5 shells (2 3/4" or 3"), keeping ammunition easily accessible during hunting or range use. Constructed from durable glass-filled polymer, it ensures long-lasting performance even under heavy recoil.
Built from lightweight aircraft-grade aluminum with a satin black finish, this combo is designed for durability without adding unnecessary weight.
