1. Paper Towel Test: Place a paper towel inside the can and close the lid securely
2. Submerge: Place the can in a bathtub or large container of water for 30 minutes

Frequently Asked Questions About Ammo Cans

Are 50 cal ammo cans waterproof?

Yes! Authentic military surplus 50 cal ammo cans feature a rubber gasket seal that creates a waterproof and airtight barrier when properly closed. The M2A1 design has been proven waterproof for decades of military use.

What's the difference between M2A1 and M2A2 ammo cans?

The M2A1 is the standard 50 cal ammo can (12" x 6.5" x 7.5"), while the M2A2 "fat fifty" is wider (12" x 8.5" x 7.5") offering 30% more storage capacity. Both use the same length and height.

Can I stack ammo cans?

Yes! Military ammo cans are designed to stack securely. The recessed lid design allows cans to interlock when stacked, creating stable storage towers. We recommend stacking no more than 6-8 cans high for safety.

How long do ammo cans last?

Military surplus ammo cans are built to last 50+ years. Many surplus cans in circulation today are 20-40 years old and still fully functional. With proper care, they can last indefinitely.

Are ammo cans TSA approved for air travel?

Metal ammo cans are NOT TSA approved for checked baggage as they cannot be opened for inspection without tools. For air travel, use TSA-approved locking cases designed for firearms and ammunition.

Can I use ammo cans for food storage?

Yes! Clean ammo cans work great for dry food storage. The airtight seal protects against moisture, pests, and oxidation. We recommend lining the can with food-grade bags for direct food contact.

Do you sell replacement gaskets?

We do not. Gaskets are easy to replace and can restore waterproofing to older cans.

What's the weight limit for a 50 cal ammo can?

A 50 cal ammo can can safely hold 40-50 lbs of contents. The can itself weighs about 5.5 lbs empty. Fully loaded with ammunition, expect 30-40 lbs total weight.

Are these real military surplus or reproductions?

We carry both authentic U.S. military surplus ammo cans and new production cans. Product listings clearly indicate whether cans are genuine surplus or new manufacture.

Can ammo cans be painted?

Yes! Ammo cans can be spray painted for customization or to cover wear. Clean and lightly sand the surface first, then apply metal primer and your choice of paint color.
