Mac 10 by American Marksman Armory

If you look at his safety markings a bit closer you'll see the letters and lines were added in the same fashion as the Powder Springs inscription.

You're right I didn't look closely enough.

Back in the early 90's I bought two registered machinegun receivers for $510. They turned out to be M10/45 clones made by Jersey Arms. They were called Commando Avengers. These receivers were originally open bolt semi autos that ATF made them register as Machineguns. There was no provision for a stock on those receivers either. I ended up bolting in a fixed wood stock. I had to open up one end of the sear hole so a selector would fit as well. A little more fitting and I got them to work with M10/45 parts kits. They both shoot just as well as my Powder Springs M10/45. Thinking of putting a CAR/M4 Stock on them now.

The part that would drive me crazy is the markings........although it is pretty much verboten to remove/re-engrave markings on an NFA firearm, I'd actually consider writing a letter to the ATF to see if I could have the (identical) markings professionally re-engraved

And what would they say if you wrote them with I have a pistol and the serial # is crooked. May I weld up the original serial # and re-engrave the serial # straight? The answer would be the same. It could very well be that the Tech Branch might be aware of the letters being off from this manufacturer. So if they letters were straight, the Tech Branch might know that the original markings have been removed. If so, that would be very bad. The OP has a functional RR M10. I think sending it to Sam would be a good thing.

WOW, off line for a couple of days and everyone chimes in. I appreciate all the suggestions. Knew the gun was ugly when I bought it. Got it as a shooter with intentions of refinishing someday. Don't think I'll be filling and remarking. Even if I get permission first from Tech branch they can always change their mind later. Not worth the risk. I think I have an old fiberglass stock lying around that will fit. It's one made by Chote or some other vendor. I tried to install it when I first got my stamp, but at the time I did not have a stock block. Having custom stock adapters is not the end of the world, just a pain in the posterior. Have to make sure I mark which stocks work with which Macs.

I have not shot it with the Lage upper installed. Once I do, I may want to move up my plans to refinish. In which case it will probably go to Sam. At which point I will have to decide how much work I want done.

The AMA Macs were flats that were bent and registered prior to the 86 ban. The only marking on them were the Cobray emblem, the serial number, and "Roseville Ca" which was very lightly engraved on the bottom of the receiver. Dan Shea had a bunch of these advertised in Machineguns News for $200 in the early 90s. Most were probably home builds but I believe Sam has built up a few. This one here is definitely not one of his but Im sure he could do it some good. None of the crooked stampings are original so I don't see why they couldn't be welded up and reengraved.

the manufacturer of this weapon is American Marksman Armory....and legally their markings and serial number are elsewhere on the gun

As this was built from a flat by AMA, the MAC / Powder springs markings are no different than a bird, or pretty flower engraved on the side of the receiver....but as a precaution, It wouldn't be a bad Idea to receive approval to remove/re-engrave them if by chance they had been listed on a previous Form 1/2/3/4....

It is my limited understanding that for a Title I firearm, the only marking that can not be altered is the serial #. With a Title II (in this example this RR machinegun) the manufacturer's name, city, state model and serial #. Now if the original manufacturer marked the receiver with hand stamps, even though they were not "Powder Springs" would those still be considered original markings by the Tech Branch? I don't know. But as previously stated even if the owner had a letter as to changing or even removing extraneous markings, if the letter got lost, could the Tech Branch change their ruling? I don't know. But I would rather leave it the way it is than change any markings. That is just opinion.

None of the hand stamped markings are from the original manufacturer including the serial number. All of the original markings are located on the bottom of the receiver just ahead of the trigger gaurd.
