Description
The King Competition Gen 7 is the current version of the 8-round magnetic shotgun shell holder designed and built in Finland by IPSC world champions. Shells sit inside the skeleton frame and are held by magnets; a short straight pull releases them completely, with no friction to drag against. Each 4-shell unit self-levels on its own, so birdshot, buckshot, and slugs in standard 12-gauge 2-3/4″ hulls all sit at the same grab height without adjustment. Spring tension and travel can be fine-tuned at the main bolt if you want to change it, but the factory setting covers standard competition loads.
What changed from Gen 6: the backing plate is now a lighter high-strength polymer, and the mounting adapter was redesigned for more strength and a wider adjustment range. The adapter and its two M5 mounting screws are in the box, so a Blade-Tech Tek-Lok or Safariland ELS receiver is the only extra hardware needed to get it on a belt. Assembly weight is 266 g. The backing plate is curved on an angled axis to follow your waist, shells are staggered for a right or left hand grab (choose the grip when ordering), and the spacing supports quad loads, dual loads, or any mix.
Fitment: Standard 12-gauge 2-3/4″ competition shells. Not intended for 3″ shells. Mounts to a belt through the included Gen 7 adapter with a Tek-Lok or ELS (sold separately), or directly through the skeleton links with M6 screws. The skeleton frame without an adapter complies with the IPSC 75 mm rule; mounting through a Tek-Lok or ELS may exceed 75 mm from the belt, so check your division rules before running an adapter in IPSC.

Who it’s for
3-Gun, multigun, and IPSC shotgun competitors running tube-fed guns who load by quads or twins and want retention that holds through movement without a heavy release.
Who should skip it
If you want a lower-cost caddy for occasional shotgun stages, the Carbon Arms 8 Round Shot Shell Holder uses clip retention at a lower price. If you want a lighter rig with more capacity, the King Competition Carbon 12 Round weighs less than this 8-round despite holding four more shells.
