Remember the ARM Bushmaster Pistol made for downed air force pilots in Nam, etc. ? Used to be and still is the logo inside the snake on older Bushmaster, looks like a bullpup....headbang.gif..I GOT ONE!!  Serial #J004##.   Great design, and super light weight.  It's a shooter!!!! Can't hit a darn thing with it and its louder than my ex wife, but awful neater too. Its the final version of 3 with the safety placed a ways back... has everything but the sear and sear hole, so its semi autohis



PISTOL GRIP

The major difference between the Bushmaster and other pistols is that the pistol grip is forward of the magazine. A unique design feature, the patented swivel grip, allows the Bushmaster to be fired by both left and right-handed shooters.

The Bushmaster is fired by firmly gripping the pistol grip, grasping the receiver, and twisting the pistol so that while the pistol grip is vertical, the receiver twists 40 degrees right or left. For righthanded shooters the receiver rests on the riaht forearm, with the ejection port to the right. For the left-handed shooter, the opposite applies.

In order to swivel the Bushmaster, firmly grasp the pistol grip in one hand and the receiver in the other and "twist" the receiver in the desired direction.

In this position, the Bushmaster is now ready to fire.

Mr. Gwinn designed something that makes me proud to be an American, i'd say.  Thanks.

Here is a link that has good info Yak.

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.

By consistently and methodically applying these principles, it has been possible to make a high percentage of all individual parts in the various weapons comprising the Bushmaster system identical and thus interchangeable both among our various models and with the Colt M16.

The overall concept of the U. S. M16 and Soviet AK-47 have been in military use for many years and both countries continue to produce these proven designs in large quantities. Along with these concepts, the utilization of all practicable new developments in the field of weapons technology, improved materials and the empl.bymenVs of the most advanced machine tools and special equipment insures that the shooter has at his disposal a weapon of .. sophisticated design and technology.

Believe it or not, I think the inventor of the Arm Pistol posts on this board.  Last name is Gwinn, can't remember his first.

Ja!  Rly!!!!

Just for those who don't know, the original Colt gun actually recieved a designation by the USAF of GUU-4/P.

Nice! That would be a cool suprise for a VC with a rice hoe coming to capture a pilot that just landed...

I don't know if Gwinn posts here, but his sales guy, TWL does.  The guy that runs MGI is the one that invented the gun IIRC.

Darnit, I can't find the thread, but there was a pretty big one a while back and TWL posted all sorts of history on the design, it was fricken' fascinating...

My cousin had one of those, damn was it loud!

so...  why arent clones of this being produced today I sometimes wonder?



or are they?


I saw one years ago and looked for one to call my own, but didnt have any luck finding one..

thanks for taking the time to post.  

First name is Mack, founded Bushmaster to later sell it out. Still operates as a firearms developer under the business name MGI which does advertise here. I have spoken with him a couple times some years back.

"Imp" or "Imp gun" comes from the fact that the original Colt gun was first chambered in .221 IMP.  By the time Bushmaster got ahold of the design, it had been rechambered to .223 Remington.  I think someone here (or maybe it was somewhere else) stumbled upon a picture of the rifle that Bushmaster reverse engineered from the pistol too.

had one myself, really cool piece but i could not hit anything more than 5 foot away. It has a very high "cool" factor as a collector piece.

Looks like mine, but you have the (better?) rear sight assembly.





One important thing to remember about these are they ARE chambered for the .223 Remington and NOT the 5.56 Nato! Don't shoot surplus ammo in that thing. You'll pop/pierce primers. Wanna' know how I remembered?

I always remember the ad in the back of magazines showing the guy with the Helicopter crew helmet standing in the doorway of Huey with a string of brass blazing out of the side of that thing...

SBR? isn't it full auto?

Wanna' know how I remembered? han.  yeah the rear site i have swivels to match the turn of the front site, and boy howdy i can really pop them cans at 300 yards j/k lol.....lol.....thanks for the advice on the ammo, I did not know that.  I m gonna give mine a bath now. lawdawg430 i love my dogs

I don't know if any were made in select fire, but it could have happened. But these are PISTOLs baby!! Not Short Barreled Rifles.

lawdawg, glad you can hit things that far out. With the crappy things that pass as sights on mine I'm lucky to hit house sized boulders at that range.

I was being  sarcastic BBEEBOB,hit

You know, those might be cool retro guns but, I'm sorry, those things are ugly! Of course that's just my opinion. In a last ditch effort it would be better than throwing rocks.

Doc

awww c'mon now.   its like the bushy M17, just without that hideous plastic stock.


I was actually contemplating trying to build a clone by hacking off the reciever extension of an 80% tannery receiver, but couldnt come up with an effective (and cheap) way to replicate the gas piston system...


are they ugly as sin? well yeah kinda.  but theyre also unique.  I wouldnt mind seeing something slightly different out there, even if it is just a blaster with little practical purpose..

An Armpistol is on my list to get.  Everytime I see a nice one I don't have the cash and when I have the cash I can't find one and end up getting something else.  One of these days...

(notice the XM177 flash suppressor... )

This is from the Summer 1976 isue of SOF. Just a coincidence: there is an article on the arm pistol in that issue.

Fitter - Any chance you could scan the article and post or email it?  I would love to see it.

Will do. Later today.

The SOF article:

Very nice, shot one back in the early 80's that was for sale but did not buy it.

Fitter - YOU ROCK!  Thank you very much!

Thanks Fitter!

Fitter, thanks, super cool.
