FN Partners With Dillon Aero For Modular Aircraft Gun Mountings

From the press release:

(McLean, VA – October 13, 2014) FN Herstal, a world leader of small caliber weapon systems, teams with Dillon Aero to add to its portfolio of FN MAG® 58M and FN M3M™ (GAU-21) machine guns, the Dillon Aero M134D Gatling Gun as an additional option to its airborne pintle mounted systems. FN Herstal airborne pintles are now capable of connecting either to the FN MAG® 58M, the FN M3M™ or the M134D, with all three variants being qualified by FN Herstal. Each armament conversion kit fulfills a segment: the FN MAG® 58M is a 7.62mm cal machine gun with maximum rate of fire of 1,000 RPM; the M134D, also known as the “Minigun” is a 6 barrel Gatling Gun with rate of fire of 3,000 while the FN M3M™ (GAU-21) is a .50 cal firing at 1,100 RPM.

The armament swap on FN Herstal’s systems connections will only take minutes. Swapping from the FN MAG® 58M to the M134D or to the FN M3M™ (GAU-21) on FN Medium Pintle Systems adds flexibility to the end users. Providing end users with the ability to configure the weapon systems with the armament of the customer’s choice greatly improves the helicopter’s modularity and adaptability to specific missions and threats. By offering three variants and turning its airborne pintle mounted systems into modular systems, FN Herstal covers all calibers and segments that are of interest to its customers, and opens a growth path for future weapons solutions.

FN Herstal is a world leader in the design, development and manufacture of small caliber portable weapons and weapon systems, and equips more than 2,600 airborne platforms on all continents.

Dillon is of course the big name in miniature Gatling guns for aircraft (especially helicopter) applications. Switching between a GAU-21 and a Minigun on the same pintle mount sounds very handy for whirlybirds that regularly find themselves in harm’s way.

    I had never seen the M3M before. Interesting MG.

      Shorter lighter barrel and fires from an open bolt if I am not mistaken.

    • FN’s M3M and M3P are updated versions of the WW2-developed M3 machineguns, which were created because the rate of fire of the aircraft configured M2 machineguns were considered to be too slow. US Army Ordnance wasted a lot of time insisting that any changes to speed up the rate of fire still allow for reverse compatibility with the existing M2 configurations. Ultimately, significant changes were allowed, but the resulting M3 was not accepted as a Limited Standard until April 1945. The M3 design was credited to the Frigidaire Division of General Motors.

    Is that a little Eotech on top of that big-ass-gun?

    • SP mclaughlin

      Unlike Battlefield, real door gunners don’t have crosshairs implanted in their eyes.

        I thought you just yelled “Get some! GET SOME!” while using the bullet impacts and tracers to see where you are hitting.

        Source: Me, but I am not a doorgunner. Not even a regular gunner.

        Any real gunners to confirm?

        • Miles

          Actually, I preferred a 200P IZLID laser on a rail mount to get those first rounds on target. After that, you can use tracers, but those first round downrange can make all the difference.
          EoTechs are lots less expensive though, but it all depends on what the gunners can convince the CO to buy and the armorer to attach.

          how can you shoot women or children?
          easy, you just don’t lead ’em as much

            That joke so dark I could make some racist jokes about your joke.

    • MattInTheCouv

      the only specops unit i find myself hanging around from time to time has an eotech-esque optic that sits atop their m240b’s, and i imagine the ma deuce’s as well. it has like 3 or 4 times the glass real estate, though. i’ve never seen its reticle

      • Miles

        That’s a B.E. Meyers DCL 110 or 120 sight.
        Very nice, but really overkill for a 240.

        • MattInTheCouv

          Yup, that’s the one. As far as I know they are only on their vehicle mounted MG’s
