The Case Club FN M249S Rifle Case is the best M249S / M249S PARA case on the market, bar none. The precut foam will fit the FN M249S or PARA version of the rifle, 2 box magazines, 3 thirty round magazines, the bolt locking device, a semi-automatic pistol, 2 pistol magazines, 2 silica gel canisters (included), a waterproof accessory box (also included), and an extra stock and upper barrel assembly. The foam can also accommodate optics on the rifle and underbarrel attachments on the pistol. The case itself is waterproof, dustproof, & has a built in pressure equalization valve for changing altitudes. It is heavy duty so it can be shipped or checked on an airplane and can handle all the abuse from TSA agents. Built in heavy duty twist latches ensure nothing gets in or out. Padlockable holes are also built right in, which can take standard sized Masterlocks so you can be guaranteed this case is safe & secure. The foam insert is closed cell military grade polyethylene which can be wiped clean if wet or oily. The foam is perforated in key areas so you can remove the foam (with included knife!) as needed to customize the insert for your unique optics. The rifle magazine cutouts can hold either 10, 20 or 30 round regular or pmag magazines. Reusable silica gel canisters are included to remove moisture from within the case. Once the silica gel is saturated just pop it in the oven to cook out the moisture & use it again. A waterproof accessory box is also included, and it is perfect for storing your cleaning supplies and small tools. This case is compact, organized, & uses all available space to the fullest.
