It is my limited understanding that MAC didn’t make semi auto pistols. Open bolt semis were from RBP. The RBP semi auto serial number starts with SA. YMMV.

It couldn't have been a semi converted before 1986?

There are any number of things that could have happened. It could be a very badly done transferable from before May 1986. The problem is that on its face it is extremely suspicious. I suspect it is actually an unregistered receiver that has been "forced matched" to some existing paperwork for a destroyed/lost/etc. transferable. If so, it is basically worthless. Well, it is worth a $250,000 fine and 10 years in federal prison, but not anything else.

It won't be cheap, but that's repairable. S/N will need to be verified before I'd touch it.
CAN NOT be laser engraved. The numbers have to be done with an engraving machine in the proper font and size.
BATF insists the numbers be .003 into the metal and is quite specific about those facts. That location is where it goes. You can acid etch and make out some previous numbers sometimes to verify the new number is even in the ballpark relative to existing factory numbers. A GORTON PI-2 is what is required and the steel will need to be TIG'd (build it up) and milled or surface ground flat. Just coming from an old machinist................takes HOURS.That is an abortion though.

MAC did make a semi auto. It was a carbine and it was closed bolt hammer fired, it was designated the M20 and only a few were sold. This gun is not one of them and it’s irrelevant. This gun is a powder springs SMG that was defaced

I know a guy who has an RPB M11 that was stolen by the hells angels in the 80s, they cut the serial number portion out of the gun completely, it was recovered and the serial number chunk was welded back in (the original number and original stamp). His gun is good to go, but this one is not. I saw this one on GB and was skeptical about its legality with the original number having been defaced. If he has paperwork on the gun that has the SN listed he would have been way better off just welding that milled out SN, and restamping it in the correct spot, neatly, and nobody would have questioned it. Instead it looks like it was done in someone’s basement with a dremel and it’s definitely illegal like that with the original number still clearly milled off 🤣

I would certainly defer to your experience of research. Did PS use the same weld in style frame for the searshaft similar to the RPB weld in frame?

No, they did not as it was not an open bolt gun and it had totally different fire control parts. It was hammer fired closed bolt and it had a selector switch permanently welded into the frame.

... What kinda total idiot does that to a MAC? Smh

 

[skiboatsp]

It's interesting how somewhat knowledgeable people will give clearly illegal advice to people online in gun forum no less.

The gun is in otherwise good shape, internals look excellent, original even. Cool story if someone competent restores it to 'spec', and gets it back into NFA circulation.

Perhaps they kept their MAC, sold this in its place, and thought they were a genius?

Regardless, I wouldn't want to be in the same room with that lower.

EDIT: Looking more at that photo, it could also be a theft recovery. Forensic detectives often use acid to try to reveal mangled serial numbers/trace guns. In that case, perhaps the gun was returned to the owner by police, and since the owner had not personally obliterated the SN, they were able to keep the gun, and re-stamp.

Furthermore, if it was on a trust, the owner's trust would be engraved somehwere, lending further proof of ownership.

My Gammy could've done a better repair. Hell, a 5th grader with some Bondo and Krylon could do better...

On a F4 item you do not engrave the trust or makers info. Only on a F1 do you engrave the makers information. The maker can be a trust.

I have several items on a trust that are F4 and several F1. The trust is the "maker" for the F1 items and they are such engraved. The trust did NOT make the F4 items and as such those are not engraved with any information for the trust.

Over on ARFCOM they used to post/give out the WECSOG diploma for such workmanship on firearms. Wiley E. Coyote School Of Gun Smithing.
