TacStar Shotgun Rail Mount with Sidesaddle for Mossberg 12 Gauge

The TacStar Shotgun Rail Mount with Sidesaddle for Mossberg 12-gauge shotguns adds a full-length Picatinny rail to the receiver top while providing quick-access shell storage on the side. This dual-purpose mount allows you to attach optics, lights, or other accessories via the rail while keeping extra rounds readily available. It's designed for home defense, law enforcement, and tactical applications where fast reloads and accessory mounting are priorities.

The mount replaces the factory receiver cover and installs with basic tools—no permanent modifications to the firearm. The sidesaddle holds shells securely with elastic retention, keeping them accessible without rattling. Constructed from durable polymer and steel components with a matte black finish that resists corrosion. Installation requires removal of the trigger group but is straightforward for anyone comfortable with basic shotgun disassembly.
