The unique TacStar Sidesaddle mounts extra rounds on your shotgun in a convenient and accessible location for fast reloading. The Hytrel® polymer shell carrier is attached to an aluminum mounting plate that installs directly on the shotgun receiver. All mounting screws are included, no gunsmithing required. Installation is easy, and in most cases requires no alterations to the shotgun. 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. The 4-round sidesaddle will also work smoothly with all models without modification. Works great as a separate Shotshell Storage Caddy for Duck Blind, Boat or Hunting Cabin!
