MTM Case-Gard J20M41 Multi-Caliber Ammo Box Clear Smoke 20 Round

The MTM Case-Gard J20M41 delivers secure ammunition storage with crystal-clear visibility and proven polypropylene construction. This slip-top design accommodates multiple rifle calibers while maintaining quick access for range sessions and field use.

What Makes This Different

Unlike cardboard boxes that deteriorate with moisture, the J20M41 features injection-molded polypropylene that resists impact, chemicals, and temperature extremes. The clear smoke finish allows instant round identification without opening the container. Individual round compartments prevent brass damage and powder contamination that occurs in bulk storage systems.

Key Features

• Clear smoke polypropylene construction resists cracking and UV degradation
• Slip-top design enables one-handed operation with secure closure
• Individual compartments fit multiple rifle calibers from .243 to .300 Winchester Magnum
• Stackable design with textured bottom prevents sliding during transport
• Hinged lid stays open at 90 degrees for easy loading and unloading
• Molded-in label area accepts permanent or removable identification
• 20-round capacity maximizes storage while maintaining compact footprint

Field testing demonstrates reliable performance across temperature ranges from -20°F to 140°F without warping or seal failure. The compartmentalized design prevents cartridge movement during vehicle transport, maintaining consistent seating depth for precision shooting applications. Competition shooters benefit from the quick-access format during timed events, while hunters appreciate the weatherproof seal that protects ammunition in harsh outdoor conditions.
