The MTM Case-Gard FL142 is a foam liner designed to upgrade the storage and protection of your ammunition inventory. Whether you're organizing a 100-round ammo box, consolidating inventory across multiple smaller boxes, or looking to minimize movement and noise in your storage setup, this half-inch thick foam insert offers practical protection for your rounds and a cleaner storage solution than loose cartridges rattling around in a hard plastic box.
Foam liners solve a common problem for shooters who store ammo long-term: loose rounds can shift during transport, stack unevenly, and allow bullet points to contact the box walls—potentially causing deformation or inconsistent seating depth when you load them later. The FL142's thickness and density cushion your ammunition while keeping everything organized and in place. For high-volume shooters managing multiple calibers, a lined box makes it easier to grab what you need without fumbling through a loose pile of cartridges.
MTM designed this liner to fit the R-100 ammo box footprint, but its dimensions also allow you to cut it in half, giving you the flexibility to line two standard 50-round boxes or one deluxe H50 box instead. That adaptability means one liner can serve multiple storage configurations as your needs change. It's a low-cost upgrade that pays dividends if you move your ammo between the range, the field, or home storage regularly.
