Ammo Case with Tilting Inserts(223, 243, 308, 3006)

Important: Slide the holders into the box with the high end of the insert to the back of the box. If this is placed incorrectly, the lid will not hold the insert in place.  Insert the insert retainer into the slot into the box bottom to prevent the insert from falling out.

Model Description

This is a modular 25-round storage system designed for 223, 243, 308, and 3006.

All cases use a universal base, with interchangeable components for each caliber:

-Dedicated 223 insert

-Shared insert for 243 / 308 / 3006

-Specific lids for different lengths

-Embossed latches for quick identification

Each case holds rounds in 5 rows of 5, with a forward-tilting insert (~30°) for easy access and improved visibility.

When closed, lid-mounted retention arms secure the inserts, while dual latches provide a firm and reliable seal.

A compact, organized, and practical solution for storing and transporting ammunition.
