I saw this for sale and was wondering if Bushmaster would still offer factory repair services for such an MG likely produced in the 1970s. Is there any other specialist armorers familiar with this type of item? From what I gather, the design uses some parts from the AR15/M16 fire control design.
Does anyone have pictures of this weapon platforms' internals?
Are those takedown pins on the back half?
One heck of a sturdy gas tube, or is there a piston drive up atop the barrel?
The seller has had it listed for several months now.

I'm leaning towards no factory service from Bushmaster, because the Bushmaster that is in business today is a different company than the Bushmaster that made that firearm.

IMO, unless you really NEED that particular gun, you can do a lot better on price buying one of the new Bushmaster "pistols." Of course, that would be semi-auto instead of full auto. I think you could get a new one for less than $2,000.
:uhoh:
However, I may be mistaken.

$13,000 is a LOT of money.

Where does this thing eject?

The ONLY point to buying this, and the only reason for the $13k is because it's a transferable full auto.

There's a number of full auto experts who could work on that if something went wrong. If you can pay $13k for an mg, you can probably pay whatever they're asking to fix a problem.

It ejects out the top. The receiver and gas piston tube rotate behind the pistol grip/trigger group so that it can be fired with the right or left hand. Mack Gwinn was the inventor and worked for the 'original' Bushmaster company. They also made a semi-auto version that can still be had for ~$1K or a bit less. More of a collector's item than anything else. I had one but sold it after the novelty wore off. It was originally designed (I believe) as an aircrew 'bail-out' weapon because of its short length. Keep in mind, it is a PISTOL in the SA version and not designed to be fired from the shoulder. You actually laid it along your forearm and sighted down your arm with the arm fully extended. That is why it was know as the "Arm gun".

The ad has been up on the sturm board, on and off, for about a year or longer.

Where do you put the support hand? Under the receiver?

You can use a two-handed grip on the pistol grip, as you normally would with any other 'pistol'. Or you could hold onto the magazine. Or up under the receiver, I guess, if that worked for you. The gun is designed to be fired with the arm fully extended and the receiver lying along your forearm. If you bend the shooting arm, you could cradle it in the crook of your elbow. Pulling it back to your shoulder and holding the receiver from below against your shoulder might work, but it was not "designed to be fired from the shoulder" to keep the barrel short without being subject to the NFA.

As I said, the novelty wore off and I sold it. If it had been more practical (or even had a higher CDI index) I probably would have held on to it.

WHAT GUNS

Hey yall first post. I just bought one of those yesterday. One of the second series semi-autos of course. When i first saw it i tried to shoulder it like a bullpup. Believe it or not bushmaster still has new old stock parts for the armpistol. From what i understand they were issued with a magnet that straped onto the users arm to hold the reciever flush though it doesnt need it. Apparently it often got replaced with velcro.

Here is a link to the manual and some other info.

"Believe it or not bushmaster still has new old stock parts for the armpistol."

This is not exactly true. Before I was laid off from Bushmaster we had SOME Arm pistol parts but not much left. I was literally giving parts away to people that needed anything we still had in stock. I knew that once all of that stuff ended up stuffed on a pallet in the back of Remingtons plant it would never see the light of day again (just like the $30,000 worth of M17 Bullpup parts we shipped down there). If you called Bushmasters customer service and asked about the Arm Pistol they are probably going to say Arm...what?
Arm pistol parts can only be found on used guns. Anyone paying 13 grand for the above submachine gun better have at least one spare ARM pistol for parts. The one above is also a first model so some of the parts are different than the later versions.
