These heavy-duty silicone bands were designed to add grip to magazines so indexing them is easier during reloads on training days. Bright colors are utilized for differentiating between rifle round calibers, brands, or live ammunition vs marking rounds. This material can also be written on for further customization with a Sharpie or paint pen.
