These are the newer CASE-GARD ammo boxes.
Made of virtually indestructible polypropylene that will not warp, crack, chip, peel, expand or contract, MTM CASE-GARD rifle ammunition cases are still the first choice of rifle enthusiasts throughout the world.
 
Full length mechanical hinge that is guaranteed for 25 years. Snap-Lock latch protects contents from accidental spilling.
Textured finish makes it easier to grip and harder to scratch.
 
In the late 1960's, the original RS-S-50 was designed specifically for bench rest shooters. The CASE-GARD 50's, are now available in eight sizes will hold .22 Hornet to 375 Remington Ultra Mag., with each cartridge resting in its own individual compartment. Each CASE-GARD 50 ammo box is supplied with a load label for recording load and sight data. All rounds listed as bullet up, unless noted. See ammo box charts for more calibers.
 
All MTM Case-Gard ammo boxes are MADE IN USA in our factory in Dayton Ohio.
We now use a full length mechanical hinge on most of our R-50's.
