Our Pocket Armory adapters are now available for 22 Magnum!

We are glad to introduce our all new product, Pocket Armory !

How prepared will you be when ammo runs scarce?  Your gun is only useful for as long as your ammunition supply lasts.  And any spare ammo won't be good if you aren't carrying a gun that will fire it.  That's why we developed the Pocket Armory adapter system.   You'll never have to worry about whether you've got the right gun at hand. Six specially designed ammo adapters turn one 12 ga shotgun into a 10-gun arsenal at a fraction of the cost.


Small and portable, Pocket Armory adapters come in a sturdy and convenient canvas carry pouch that can be easily stored.  They are pistol-length and now made exclusively of stainless steel!

Each adapter comes fully rifled for deadly accuracy.  cutoutOur Extractor-Grip cutout feature allows for removal of spent shells while o-ring retention keeps the adapter in the chamber.

With the Pocket Armory system, you can shoot any of the following ten calibers from your 12 ga shotgun: 12ga, 20ga, 410 bore, 45 Colt, 44 Mag, 45 ACP, 38 Special, 357 Mag, 9mm, 22 Mag, and 22 LR.  It is the perfect solution for firepower versatility.



You'll never find another system quite like this one and at an affordable price.  Don't get caught unprepared, order your Pocket Armory system today!
