For lining ammo boxes, the foam liner is a ½" thick and is great for reducing rattle, as well as protecting your bullet points. Each liner is large enough to line MTM Case-Gard ammo boxes from our smallest to our R-100 ammo box. Or, it can be cut in half to fit into two regular 50 round ammo boxes or one deluxe H50 ammo box.
