    Default Gwinn ArmPistol

    Here is a very early Gwinn " Bushmaster " Armpistol. Came in today, I had to buy it. Apparently made in early 70's as a military survival pistol. .223 with a swiveling magazine / housing system. Uses AR parts. Cool Cool Cool.

    I saw one of those a few months back at a gun show, owner said it was made for the USAF. The swiveling lower receiver was weird, and he wanted 1100$ for it. I wonder how many were manufactured?

    Very nice find..........yours is (I believe) the first of 3 different models. Safety above trigger is first, then Safety in trigger guard, then on the receiver.

    Some were purchased by the USAF. In satin nickel! When a new commander took over, they were pulled from inventory. I would assume, distroyed.
    Before starting any serious collection: Spend your first thousand dollars on reference material. It's money in the bank.

    I have no problem, going out the same way.

    Very nice find !

    Let us know how it shoots !

    I remember these. An article in Guns magazine, absolutely. A "Survival" weapon for pilots. Originaly chambered, I believe, in .221 Fireball. Switched to .223 after M-16 adoption. The rear of the pistol was to be clamped to the arm with the non-firing hand making the arm the "Stock". Supposedly accurate to 100 Meters on man sized targets. The muzzle blast was said to be excessive.

    Default Gwinn Arm Pistol mechanics

    Bought a 1st variation a few months ago for a really reasonable price (should have been the first clue there was a problem). So far I have replaced the bolt assembly (it does take AR components) and am now trying to sort out the fire control components. The piece that normally is a modified trigger is made of stamped metal with an extended arm that connects to the forward located trigger. I suspect this part to be the problem. Does anyone have a diagram or pictures that shows the fire control components. I had one of these a long time ago and never had any problems with it so I never took it apart. Any information or advise would be appreciated.

    My earliest memories of firearms concerns my sisters god father trying to sell one of these at the CA Pomona Gun Show.

    Oh c@#$%! Sounds like the same problem with my AK Bullpup and every other Bullpup kit I've heard of. The connector needs to be very rigid and tight. If it fires when you yank the trigger but not when you squeeze it, that's the problem. Excessive basic trigger weight may also make it tough to fire.
