MTM's AC4C is a Rugged tactical carrying crate for multi-caliber ammo storage and transport. Comes with four, O-ring sealed 30 Caliber ammo cans (AC30T) for multi-caliber ammo storage. 30 Caliber ammo cans are a convenient size to store all types of bulk ammo. The only problem is, that they are easier to knock over than the larger ammo cans. Now you can stack them as tall as you want in these specialized crates. Made of rugged polypropylene to last. Stackable and strapable with four tie down spots for ATV attachment. Showing up at the range with one these, will be like saying, don't ?#%! with me. AC30T ammo can features include: • Water-resistant O-ring seal • Double padlock tabbed • Molded-in stacking ridges • Heavy-duty, latching systems • Inside: 3.4”(L) x 8.9”(W) x 6.1”(H) • Outside: 5”(L) x 11.3”(W) x 7.2”(H) • Designed to hold up to 15 pounds of ammo. All MTM Ammo Crates & Cans are made in our factory in Dayton Ohio. They will have molded into the plastic on the bottom "Made in USA" marked on them. Beware of the imported knock offs
