MTM 100 Round Rifle Ammo Box (17, 204, 223, 5.56×45, 6×47)
The MTM box is designed for 17, 204, 223 Rem, 5.56 x 45, and 204 Ruger calibers with a scuff-resistant surface and a maximum overall length of 2.65 inches. Best for individual shooters who value a reliable, compact storage solution with a secure snap-lock latch. This box supports easy stacking and transport during practice sessions. A limitation is that it stores up to 100 rounds, which may require more boxes for bulk sessions.
5.56mm Ammo Case Storage Box: 2-Layer Waterproof Rifle Case
Designed for serious shooters, this dual-layer box holds up to 1004 rounds of 5.56 (.223). It features an extreme-duty PP shell, IP67 waterproof sealing, and a rugged design for truck beds and outdoor deployments. Best for bulk prep and extended range sessions. A caveat is the larger footprint, which reduces portability for travelers needing a compact case.
MTM 100 Round Rifle Ammo Box (Same family)
This MTM model offers a 100-round capacity with a scuff-resistant textured surface and a snap-lock latch, plus stacking feet for stable storage. Best for shooters who want repeatable, dependable organization for multiple calibers, including 5.56×45. Choose this if you need easy vertical stacking and a robust grip for frequent handling. A potential limitation is similar capacity to other compact cases, potentially requiring more units for larger lots.
MTM 50 Round Rifle Ammo Box (Brown Small)
The MTM 50 Round Box remains a favorite for compact, versatile storage. It supports a broad range of calibers and features a textured finish for grip, a Snap-Lock latch for security, and stacking feet for organized shelving. Best for enthusiasts who need a lighter case for field trips. Limitation: holds fewer rounds than larger boxes, so it’s not ideal for bulk storage needs.
Kinghardcase 600 Rounds Ammo Case
Kinghardcase’s 600-round case uses a durable ABS shell with a double foam interior, designed for 5.56, .223, and .300 ammo. It’s ideal for bulk transport and organized storage, featuring a top rope carry handle and bottom alcove for accessories. Best for bulk shooters or training facilities. Avoid this if you need ultra-lightweight transport for quick trips, as it’s heavier than smaller cases.
Kinghardcase 200 Rounds Ammo Case
This box holds about 200 rounds with a soft foam lining, an outer ABS shell, and a sturdy carry handle. Best for medium-sized transports and quick-access storage. Choose this if you want a balance between bulk capacity and portability. A limit is that it holds less than Kinghardcase 600-round models, making it less suitable for very high-volume needs.
Buying Guide: Key Considerations For Selecting a 5.56 Ammo Storage Box
- Capacity vs. portability: How many rounds do you need to store at once, and how often will you move the case?
- Durability: Do you need an impact-resistant shell, waterproofing, or dust protection for field use?
- Interior design: Are foam or desiccants important to prevent movement or moisture damage?
- Caliber compatibility: Will the box handle your typical ammo lineup beyond 5.56, such as .223 or .204?
- Locking and security: Is a snap-lock latch or triple padlock system essential for transport?
- Stackability and organization: Do you need stacking feet or dividers to keep contents tidy and accessible?
