The ramp on the stern allows SEAL teams to ride their CRRCs right up the stern of the boat, for fast extraction and insertion. To support the SOF missions in a medium to low threat environment, the Mk Vs are outfitted with five gun mounts for small caliber weapons supporting any combination of: M-2 .50 cal heavy machine guns , M240 or the M60 7 ...

Out-gassing is the reason that open-cell backer rod was developed. [7] Open-cell foam is porous so it will let gasses through which could otherwise cause blistering of the caulk or sealant. Additionally, open-cell backer rod allows air to get to the back side of the caulk or sealant which accelerates curing when used with air-cured sealants ...
