The 7 AR-15 Rifle Case by Case Club holds up to 7 M4 rifles. The case focuses on the M4 platform (aka AR-15) and caters to agencies and enthusiasts alike. It comfortably holds seven rifles (both carbines & mid-lengths). It was designed by professionals for professionals. This waterproof case can accommodate all major optics including ACOG, AIM Point & more, provided they are within 3″ high. In regard to accessories, the case has room for a front forward (vertical) grip, laser and/or flashlight provided they are not wider than 1.5″. All the foam is military grade polyethylene which is oil proof so if it gets dirty it can simply be wiped clean. The case itself is ultra high strength, waterproof, dustproof, shippable & has a lifetime warranty. A purge valve keeps the moisture out while allowing the case to be opened in high or low altitude, and each case includes 2 silica gel canisters to soak up trapped moisture and keep everything rust free. Purchase more than one and stack them up!
