The MTM clear blue 223 Rem 100-round ammo box (MTM part no. RS-100-24) is a compact, 100-round flip-top box in clear blue, made by MTM Case-Gard for the 223 Remington and 5.56×45 family. Space is tight in most shooting boxes, and this one holds a hundred rounds in a footprint of about 4.8 by 5.2 by 3.0 inches. The fit list also runs from 17 Fireball and 204 Ruger up to 300 Blackout, 350 Legend and 6×47. It is aimed at varmint hunters, competitive shooters and reloaders who want bulk storage that still travels.

Key Specifications

• Capacity is 100 rounds, a compact way to hold a large amount of ammunition.
• The box fits 223 Rem., 5.56×45, 204 Ruger and 17 Fireball, the core small-bore centerfire list.
• The list also covers 300 Blackout, 350 Legend, 6×47 and 6mm TCU, so AR-pattern and bolt-action loads share one box size.
• The color is clear blue, which makes the contents visible and the load easy to identify.
• Maximum overall length is 2.65 inches, the longest round the compartments will accept.
• Listed dimensions are 4.8 x 5.2 x 3.0 inches, small enough to fit between cleaning gear in a shooting box.
• Construction is polypropylene, which MTM says will not warp, crack, chip or expand, so the box keeps its shape in a range bag or on a reloading bench.
• A Snap-Lock latch holds the lid shut, which protects the contents from accidental spilling.
• The lid uses a full-length mechanical hinge covered by a 25-year guarantee, which is the part of a flip-top box that usually fails first.
• Each box comes with load labels, so you can record the load and sight data for the rounds inside.
