MTM CASE-GARD J-20 series ammunition cases are a favorite of rifle enthusiasts throughout the world. Made of virtually indestructible polypropylene that will not warp, crack, chip, peel, expand or contract. The CASE-GARD J-20’s are available in five sizes. All rounds are listed bullet up position. The "Slip-Top" case is designed to keep 20 rounds secure in a jacket or shirt pocket. J-20s also offer a great way to keep special loads separate.
