MTM Case-Gard RS5010 50-Round Ammo Box for .223 Rem & .204 Ruger - Green Polypropylene

The MTM Case-Gard RS5010 50-round ammo box is a rifle ammunition storage solution built for shooters who demand durability and organization. Whether you're stocking .223 Rem, .204 Ruger, or any of a wide range of rifle cartridges up to 2.65" OAL, this green polypropylene case keeps your rounds secure and easy to locate at the range or in your reloading space. MTM's design philosophy—refined over decades since the original benchrest-shooter boxes of the 1960s—prioritizes practical storage that protects your investment without fuss.

The construction is straightforward and built to last. Polypropylene resists warping, cracking, and the wear that softens lesser storage boxes over time. Individual compartments cradle each round, preventing rattle and damage during transport or storage. The mechanical hinge is guaranteed for 25 years, and the Snap-Lock latch keeps the lid secure so contents won't spill if the box is jostled. A textured finish grips your hand better than smooth plastic and resists scratches—practical details that matter when you're handling ammunition regularly.

Each box ships with a load label for recording your custom loads and sight data, useful whether you're documenting factory ammunition or tracking your own handloads. Made in the USA at MTM's Dayton, Ohio factory, these cases are trusted by serious rifle shooters and reloaders who've come to expect reliability from the brand.

Frequently Asked Questions

What rifle calibers fit in the MTM RS5010?

The RS5010 is sized for .223 Rem and .204 Ruger as the primary cartridges, but MTM designed it to accommodate other rounds with similar dimensions up to 2.65" overall length. This includes .17 Fireball, .221 Rem, .222 Rem, .222 Rem Mag, 6mm-223 Rem, 6 x 47, and others in that size range. If you're unsure whether a specific cartridge will fit, check the OAL of your round against the 2.65" maximum.

Is this ammo box good for reloaders?

Yes. The individual compartments protect your rounds during handling and transport, and each box includes a load label so you can record your powder charge, bullet weight, primer type, and other load data for future reference—a practical feature for anyone tracking custom loads.

What makes the MTM Case-Gard different from cheaper plastic ammo boxes?

MTM uses polypropylene that resists the warping, cracking, and degradation that can happen with lower-quality plastics over time and temperature swings. The mechanical hinge is built to last 25 years, and the Snap-Lock latch is engineered to stay secure. The textured finish adds grip and durability. These boxes are made in the USA and have been refined since the 1960s for serious shooters and reloaders.

Does the box come with anything else?

Yes—each RS5010 includes a load label for recording your ammunition and sight data. No additional accessories are included, but the box itself is self-contained and ready to use.
