When I decided to get a Fat Fifty Ammo Can, I wanted something sturdy, reliable, and versatile enough to serve multiple purposes. After some research and personal experience, here’s what I learned and what I suggest you consider before making your purchase.
Understanding What a Fat Fifty Ammo Can Is
First off, the Fat Fifty Ammo Can is a larger, heavier-duty version of the standard ammo can. Originally designed by the military to store and transport 50-caliber ammunition, it’s known for its robust steel construction, waterproof seal, and secure latch system. I quickly realized these features make it perfect not just for ammo, but for tool storage, emergency kits, and outdoor gear as well.
Key Features I Looked For
- Durability: The Fat Fifty is made from thick, powder-coated steel that resists rust and damage. I needed something that could withstand rough conditions and rough handling.
- Waterproof and Airtight Seal: This is crucial if you want to keep contents dry and protected. The rubber gasket around the lid seals tightly, which gave me peace of mind when storing sensitive gear.
- Secure Latch and Locking Options: The latch system is robust, and I appreciated that many models allow you to add a padlock for extra security.
- Size and Weight: The Fat Fifty is bigger and heavier than smaller ammo cans. I made sure I was okay with the extra weight and bulk because it meant more storage space.

- Condition (New vs. Surplus): Surplus cans can be a bargain but sometimes come with dents or rust. I opted for a new or refurbished can to avoid unexpected issues.
- Price: Fat Fifty ammo cans can vary in price depending on condition and manufacturer. I balanced cost with quality to get the best value.
- Brand and Reviews: I checked reviews to find brands with consistent build quality. Some manufacturers produce cans that are closer to the military spec than others.
Additional Tips From My Experience
- Consider buying a can with a removable tray if you want to organize smaller items inside.
- If you plan to use it outdoors frequently, look for one with extra corrosion-resistant coatings.
- Some aftermarket accessories like foam inserts or dividers can help customize the storage.
- Always check the gasket before sealing to ensure it’s intact and clean for the best waterproof performance.
