GAOS 19 – Geissele Automatics Super Duty

Right before SHOT Show, Bill Geissele hosted a live internet broadcast to unveil his new complete carbines. They had them At SHOT Show but the counter was two deep, waiting to look at them every time I stopped by. Fortunately, they were also displaying the carbines at GAOS.

    orange o-ring? fluorosilicone? hydrogenated nitrile? viton?

  2. Patrick Sweeney says:

    Whatever the o-ring is made of, if Bill says it will take the stress, count on it.

  3. Adun says:

    Does anyone know why Mr. Geissele chose to go with a government profile barrel on these builds over something more currently preferred?

    • woozie says:

      People prefer barrels other than government?

      • Adun says:

        I assume that you are joking, but I am legitimately curious as to why a government profile barrel would be put on a weapon that will never take a grenade launcher and does not have a bayonet lug. It is just wasted weight, or at best, misplaced additional weight which does not benefit the user much.

        • Stephen says:

          govt profile is whack as hell. Why would i want more mass in the front then in the rear? barrel whip mitigation please!!! i use heavy barrels for just about everything (all my SBR’s + some) for stiffness alone when used with cans, the weight in the govt barrel can definitely be re proportioned to the rear. Surprised the gov’t didn’t just spec a different profile going forward that works better for accuracy because the gov’t profile is far from a winner there.
