JET Blaster - 15-Round Katana Mag System Pack

The Katana Magazine System is a revolution in Compact Ammo Storage for your loadout and personal foam shooting blasters.


For years, even stefan magazines kept a large part of the normal full length magazines for compatibility with magazine fed foam blasters. It was a sacrafice needed to be usable and backwardly compatible, no more.


The Katana Magazine System use one straight this magazine half the width to store stefan darts and use a full length adapter to use in stock foam blasters. The advantage, one can store the same amount of ammo with half the bulk or twice the ammo with the same space used in a personal loadout.


In addition, these magazines come are a revolution in not only magazine design but possibly future blasters as well that could be built solely for these magazines.


This Katana Mag System Pack includes the followings ONLY:

Katana Mag Apdapter x1

Katana Mag x1


Note that the Katana Mag only works with Stefan and fits only into the Katana Mag Adapter. This product DOES NOT work in unmodified blaster that can only shoot full length foam darts. Extra Katana mags can be purchased HERE.
