Ammo Box - 300 Blackout - 50 Rounds

300 Blackout (300 BLK) Ammo Box — Built with BoxLoc

Expanding on the BoxLoc system, this version is designed specifically to store 50 rounds of 300 Blackout 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.

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.
   • Once you feel resistance, wiggle the hinge slightly along the pivot joint as you move it upward to help it seat properly.
   • Continue until the lid clicks securely into place and pivots smoothly.
2. Attach the front latch
   • Position the latch so the rounded side inserts into the lid at a slight angle.
   • Lightly squeeze the top of the latch to help it pop into place.
   • Make sure the flat side faces outward, so the finger lip curves toward the box.
   • While the latch 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.
