Ammo Box - 22LR - 300 Rounds

.22LR Double Ammo Box — Built with BoxLoc

Expanding on the BoxLoc system, this version is designed specifically to store 300 rounds of .22LR ammunition in a clean, modular format. It carries over the same smooth design language as my card boxes — rounded edges for comfort, a secure sliding hinge, and a crisp latch with an integrated finger lip for easy use.

Each ammo box includes removable inserts, making it simple to load, organize, and clean. The inserts fit snugly inside the box but can be lifted out when needed, giving you more flexibility for storage or transport. Like other BoxLoc designs, assembly is hardware-free — no tools, screws, or glue required.

This .22LR Double Ammo Box includes updated line art along with a redesigned .22LR insert that allows the ammo to “float” and be easier to access over my original design - Future plans may include internal stacking inserts which would net around 600 rounds of capacity in a single box.

Assembly Instructions

1. Join the lid and base
   • Align the lid’s hinge tabs with the grooves on the bottom of the base.
   • Gently slide the lid upward into the hinge slots.
   • When you feel resistance, lightly wiggle the hinge along the pivot joint as you continue sliding upward to help it seat properly.
   • Double version - Because it includes an additional hinge set, you may need to work each hinge section individually, guiding them upward one at a time, a little at a time, to prevent binding or potential breakage.
   • Continue until the lid clicks securely into place and pivots smoothly.
2. Attach the front latches
   • Position the latch so the rounded side inserts into the lid at a slight angle.
   • Lightly squeeze the top of each latch to help them pop into place.
   • Make sure the flat side faces outward, so the finger lip curves toward the box.
   • While the latches will technically fit either way, this orientation provides the best comfort and clearance when opening or closing.
3. Ammo Tray Installation
   • Place the insert tray into the box and press firmly down on all four corners to lock the legs into place. You’ll know it’s fully seated when the top surface sits flush all the way around.
4. Ammo Tray Removal
   • Remove one round from a corner, then insert the end of a pencil (or similar tool) into the empty hole to gently pry the tray upward at an angle. Once it starts to lift, you can continue with the pencil or grab the exposed edges to fully remove the tray from the box.
