TacStar Side Saddle for Mossberg 500/590 12 Gauge

The TacStar Side Saddle mounts directly to the receiver of Mossberg 500 and 590 shotguns, providing immediate access to six additional 12-gauge shells. This receiver-mounted shell carrier keeps backup rounds within reach without interfering with the shotgun's operation or adding bulk to the forend. Ideal for home defense, tactical applications, or any scenario where rapid reloads matter.

Constructed from reinforced polymer, the Side Saddle installs using existing receiver pins—no drilling or permanent modification required. The shell retention design allows for quick single-shell extraction while keeping rounds secure under recoil. Installation is straightforward for users comfortable with basic disassembly of their Mossberg shotgun.
