The GrovTec Shotgun Locking Swivel Set (GTSW19) is an all-steel firearm hardware kit designed to fit 1.0-inch (25.4 mm) tactical and hunting slings to pump-action and semi-automatic shotguns. Finished in a corrosion-resistant black oxide coating, this system allows shooters to convert factory magazine tube end caps into secure front sling mounting points without replacing the original cap. It includes a knurled, threaded GT locking collar mechanism that secures the sling attachment against accidental release during field movement, alongside rear mounting hardware for the buttstock.

Who is the Grovtec Swivel Set To Suit Most Pump & Autos 1" Loops Black for?

  • Waterfowl hunters — Carrying pump-action or semi-automatic shotguns over long distances requires a secure sling connection rated for up to 300 lbs (136 kg) of straight-line pull tension to handle field movement in demanding conditions.
  • Sport shooters — Retrofitting factory shotguns that lack OEM mounting hardware allows the installation of 1-inch (25.4 mm) slings using the included 3/4-inch (0.75") rear wood screw swivel stud and magazine-cap adapter.

Less suitable for: Firearm setups using sling webbing measuring 1.25 inches (31.75 mm) or wider, which require wide-loop swivel sets, or specific shotgun models including the Browning 2000, Ithaca 37, Savage 30, Sears 21, Stevens pump-actions, and Winchester 1400, which require dedicated model-specific sling mounting hardware.
