Had a chance to purchase one today (second version). What can you tell me about them and how retro are they. Anyone own one?





There are three known variants to the Bushmaster Armpistol. The pistol shown above is one of the early Gwinn Firearms market units that featured a somewhat conventional safety above the trigger assembly - this variant was produced in the early 70s.

From the Bushmaster Armpistol Manual - The Bushmaster weapons system was based on the function and operating principles of the patented IMP aircrew survival weapon designed at the United States Air Force Armament Laboratory at Eglin Air Force Base. Subsequent design changes integrated the battle proven characteristics of the U. S. military M16 and the unexcelled gas system of the Russian military AK-47; thus attaining the simplicity and functionability of the current Bushmaster production.

All I know is the grip rotates 180 so you can rest the mag on your right forearm or left forearm.

They should have made it into a bullpup.

Not that it would have been more successful at that time in history.

I can say that they made a rifle version and that there are also select fire versions in circulation.

Invented by Mack Gwinn. I think in the early 80s.

Mack founded MGI as well. http://www.mgimilitary.com/

He tells me MGI stands for "Mack's Goofy Ideas"

I have one, 3rd. version. Not real comfortable to shoot (watch that charging handle, trust me). Not surprisingly it's very loud. Gets a lot of comments at the range.

i've got the armspistol (safety inside trigger huard) and 2 of the bushmaster assault rifles, 1 with wood furniture and 1 with black wood forearm and a metal folding grip. haven't had a lot of range time with any of them but they are a cool piece of history.

now that piston driven ARs are making a comeback, what's old is new again.

here's my archived thread with some pics of them:

Works for me. All you're missing is a broken link to another thread here that has no doubt been archived too.

I acquired the final piece to finish up my Gwinn/Bushmaster collection.

Write up here
