The Berry's Flip-Top 200 series ammo boxes are 20 round rifle ammo boxes, reimagined and redesigned. The compact design makes for an excellent storage choice for your rifle ammunition and the two piece flip top box keeps your ammunition secure in any pack. All Berry's Ammo Boxes are made from high impact polypropylene for increased strength against cracking, chipping, warping, expansion, or contraction. The 20 round boxes are a great choice for those situations that don't require a lot of ammunition. They feature translucent lids and are stackable, for convenience.
