Modeled after the original military ammo cans. Water resistant tongue and groove connection. Will resist against casual moisture, dust and dirt. Protecting your firearm is one thing, but protecting your ammo is just as important. Make sure every round fires smoothly with Plano’s ammo cases and ammo boxes. Cases range in capacity from a handful of rounds all the way to a full-size field ammo case. There’s nothing worse than wishing you had just a few more shots at the range, so always come prepared.
