*by A***R on 2 November 2025*

Good quality for a good price. This is soo much better on the range than using retail 20 or 50 round boxes. My ammo is organized, easy to handle when moving about, protected from damage and the elements, easy to grasp while reloading magazines, and easy to store. I love thes ammo storage boxes. 600 rounds in one small, easy to carry, tough as nails box - easy life.
