Skb I-Series Dbl M4 Rifle Case Black
The SKB I-Series Double M4 Rifle Case is a heavy-duty hard case built to safely transport and store two short rifles or M4-style carbines. This is the case to grab when you need serious protection for your rifles during truck bed travel, range days, or long-term storage—the kind of case that takes a beating and keeps your firearms secure and organized.
What sets it apart is the rigid foam bunk-bed system inside: it cradles both rifles independently, keeping them from shifting or contacting each other during transport. The molded foam in the lid adds an extra layer of organization and cushioning for optics, mags, or other gear. The gasket-sealed, submersible design means water and dust stay out, and an automatic pressure equalization valve prevents vacuum lock when you need quick access. You'll find padlock loops molded into the case for added security, and the trigger latch system keeps the lid secure without requiring tools.
SKB built this case to last in harsh conditions: the material resists UV damage, solvents, corrosion, fungus, and impact—critical for a case that lives in trucks, boats, and gear rooms. Wheeled base and pull handle make hauling it solo manageable, even when fully loaded. If you shoot multiple rifles or need redundant storage that'll survive years of field use, this is a solid choice.

Frequently Asked Questions
Can I fit two full-length rifles in this case, or just M4 carbines?
