The MTM Case-Gard .50 Caliber Ammo Storage Can (AC50C-40) is a high-impact, rust-proof polypropylene storage container designed for the secure transport and organization of ammunition, reloading components, and outdoor gear. Manufactured in Dayton, Ohio, USA, this lightweight alternative to traditional military surplus metal cans features a tongue-and-groove lid with a compression rubber O-ring seal to safeguard contents against dust, rain, and moisture.

Key Features

• Weather-Resistant O-Ring Seal: Compression rubber gasket integrated into a tongue-and-groove lid profile resists moisture and dust penetration.
• Heavy-Duty Latching: Dual-latch mechanical closure prevents accidental opening during transit.
• Padlock Security: Molded dual padlock tabs allow the use of keyed or combination locks to meet secure ammunition transport requirements.
• Stackable Design: Molded base-to-lid indexing ridges and a flush fold-down carry handle ensure stable, non-slip stacking.
• Rust-Proof Polypropylene Construction: High-impact polymer body resists cracking, outdoor weather exposure, and corrosion.

Who is the MTM Case-Gard .50 Cal Ammo Can for?

• Range shooters — requires an internal storage volume measuring 11.0" (L) x 5.8" (W) x 7.2" (H) to carry high-volume factory rounds or handloads such as ~1,200 rounds of .223 Rem or ~1,750 rounds of 9mm in a lightweight 2.0 lb polypropylene ammunition storage can.
• Australian shooters — utilizes dual padlock tabs alongside a rated carrying capacity of 30 lbs (~13.6 kg) to maintain a compliant, locked transport container for ammunition separate from firearms inside vehicle boots and ute trays.
• Hunters and reloaders — utilizes the moisture-resistant rubber O-ring seal and internal dimensions of 11.0" x 5.8" x 7.2" to keep loose brass, primers, powder tins, and camp first-aid supplies protected from dust and rain.

Less suitable for: Dense loads exceeding the 30 lbs (13.6 kg) structural limit, which require heavy-gauge military steel M2A1 surplus cans, or full water submersion applications requiring certified IP67 submersible hard cases.
