The King Competition MSH generation 6  is a high performance modular shotgun shell holder system, designed and manufactured by World Champions. 

All of our accumulated knowledge in top level shooting and engineering has been poured now in to the 6th generation of our design. All important features are upgraded. The shell retention is again improved, but release is still as smooth. The durability and the strength of the skeleton construction and parts will now handle so much more due to long lasting investment in much stronger materials and improved production processes. The shell adjustment range is longer. New guide system will make the shell package more uniform and less sensitive to imperfect shell dimensions. Generation 6 also utilizes the new adapter system, that connects directly to the skeleton, having very rigid and 360° rotation attachment to TEK-LOK or ELS systems. Weight is reduced from previous generation.

Shells are staggered for right- or left-handed grip and are spaced with minimum distance to each other. Required belt space is also minimized. Positioning of the shells is absolute uniform through the rig and allows for consistent use of all modern shotgun loading techniques and for example mixing load-2 and load-4.

Shells are held tightly within the geometry of the holder. The short release is done by detaching the upper shells from high strength magnets. This releases the shells from the holder completely, allowing a very effortless and fast reloading. When not reloading, the system will keep the shells securely in place during running and jumping.

Each unit in the rig is independently self-leveling and allows the user to switch between all typical 12/70 cartridges. If needed, the spring tension and travel is easily adjusted by rotating the main bolt. But the standard setting will allow the user to switch between all normal competition cartridge types without touching any adjustment.

The skeleton construction makes the system very rigid and allows mounting directly to the several skeleton links with a large steel M6-thread. The rig can be mounted with bolts, hook&loop or with a adapter. All mounting hardware is supplied with the rig (adapter not included in sizes ASSM20 and bigger).

The skeleton construction and backing plate is curved on a angled axis. This allows for the larger assemblies to curve around the users waist and carried in a angle for optimal reloading with a competition shotgun belt, without the last shells exceeding the IPSC 75mm rule. Please note that using adapter for pistol belt mounting on ELS or TEKLOK system can exceed the 75mm rule and is not recommended for IPSC use.


Technical specifications:

- Cartridge maximum distance to backing plate mounting face: 57mm (add belt thickness for total distance to body)

- Useful total shell height adjustment range 33mm, useful self-adjustment range ( tensioned spring travel) 13mm

- Weight ASSM4 (135g), ASSM8 (260g), ASSM12 (390g), ASSM20 (670g), ASSM28 (940g), ASSM32 (1170g)

- Mounts with included hook and loop, M6-screws or adapter (adapter not included in assemblies size 20, 28 or 32) 

- Maximum storage temperature +80°C

I ordered my king competition shotshell caddy from Hayes custom guns and I loved the product. I use it for my 3 gun match. Hayes customer service is top notch. They help me resolve my problem with delivery of my item!

Love this holder

I tried a cheaper caddy before this and it does not compare. This holder have much better retention while giving the option to modify the spring tensions. The shells are much easier to pull away without having to drop a shell or two due to the design. Thinking of buying another 8 round holder or the 12 round version.

I ordered these king comp caddies after finally getting tired of shells not being held tight enough in my previous ones. These are great and hold the shells very well while still being a very quick and easy release. They definitely hold the shells tighter than my Invictus caddies. It feels like I’ve been getting slightly more consistent grabs too, perhaps placebo. These caddies are a bit expensive I think, though very well made. The only thing I really do not like about them is the backplate is a thin piece of aluminum that has quite a sharp edge to it - it has me a little nervous about possible cuts. Easily mediated with some tape around the edge or similar. Hayes were also awesome to buy from. Shipping was amazingly fast - I had my caddies within 3 days. Awesome shop!
