The MTM Case-Gard R-50 is a workhorse ammo storage box built for rifle shooters who demand durability and organization. Made from tough polypropylene that resists warping, cracking, and the kind of wear that comes with regular range trips and field use, this clear blue box holds 50 rounds in individual compartments—one cartridge per slot, so nothing shifts or rolls around. Whether you're loading custom handloads, storing factory ammo across multiple calibers, or organizing brass between reloading sessions, the R-50 keeps everything visible and in its place.
The full-length mechanical hinge is built to last—MTM backs it with a 25-year guarantee—and the Snap-Lock latch keeps the lid secure so you won't spill a load on your truck bed or the range floor. The textured finish gives you better grip in sweaty hands and is harder to scratch than slick plastic, which matters when you're handling boxes in a range bag or ammo can. This box ships with a load label so you can record your specific load data and sight-in notes right on the lid.
The R-50 will accommodate calibers ranging from small centerfire rounds like the .17 Fireball and .223 Rem. up to larger cartridges like the .375 Rem. Ultra Mag., with a maximum OAL of 2.65". That versatility means you can stock multiple calibers without buying a dozen different boxes. Made in the USA at MTM's Dayton, Ohio facility, the Case-Gard line has been trusted by bench-rest shooters and serious reloaders since the late 1960s—not because of hype, but because the design simply works.
