Which Kit Is Best For Me?

Shorter barrels or hunting set ups - we recommend using the +2 kit. this will give you two extra rounds without adding on too much front weight and ensuring agility during movement.

Longer shotguns / competition / where weight isnt an issue: +3 kit (3 extra rounds) or +5 Kit (for five extra rounds) are ideal for competition. (itt will be a little heavier at the front when fully loaded). This is the most popular for IPSC competitors.

Both: Combo Kit which has two different extension pieces so you can swap according to what you need on the day!
