TacStar's SideSaddle mounts extra rounds on your shotgun in a convenient and accessible location for fast reloading. The polymer shell carrier is attached to an aluminum mounting plate that installs directly on the shotgun receiver, and is designed to provide clearance for long forends.All mounting screws are included, and no gunsmithing is required. Note: some field grade shotguns may require a modification to the shotgun's forend. Shotguns using the TacStar pistol grip forend do not require modification.
