Ready: Pick Your Starting Point.

The first thing on your gear list is the gear focus. From shotgun cleaning kits to a Shockwave home defense pack, or even a steel target system, we've created the perfect starting points to accommodate a variety of situations, needs and adventures - and the list keeps on growing.

Set: Add Items To Your Bundle.

Next, is to assemble your bundle by scanning the different gear options. If it's a cleaning kit you're building, you may see a variety of options for brush calibers, solvents, and even cleaning pads. The gear options are shown in tiles and you simply need to click “Add to Bundle” for the items you need. Additional gear information will appear if you click the 'i' in the top left of the gear tile. Keep in mind, the more gear you select, the more you save. And as you grow the number of items in your bundle your discount will be shown in the top right of the screen. Here's how discounting works:

  • $25-$50 combined orders receive 5% off and free shipping!
  • Combined orders over $50 receive 15% off and free shipping!

Bundle!: Add To Cart & Purchase.

Once you add the first item to your bundle, a status bar will appear at the top showing the number of items in your bundle, a button to view your bundle summary, and sum of your building discount. At the bottom of the screen, you'll see the bundle price and simply click "Add to Cart" once your bundle is built.

And of course, if you need additional help with buidling your own custom bundle, don't hesitate to contact us.
