Buffer Tube for Wet Environments – Griffin Armament Maritime Extension

Innovation does not always have to be the biggest and bad-arse. Sometimes it can be the little things that go a long way. Qualifying for the latter is Griffin Armaments Maritime Receiver Extension for modern sporting rifles. Basically, its a standard extension, but adds more drainage holes to ensure the weapon system stays up and running after being submerged.

Instead of the common 6061, Griffin uses a 7075-T6 forging that is then machined to military specifications and then holes are added.

Those near the coast to just looking for that something extra can peruse them on Griffin’s website here.

    Or drill yourself along with a dab of Aluma Hyde II and save 30 bucks.

      @Ted Unlis Yeah, but if someone is already planning to buy a 7075 receiver extension, then this doesn't cost much more.

    Looks like a silencer.
