MPA 9mm SBR question....

[NorincoKid]

I have a few MAC's, and was considering SBR'ing one of them, for funsies.

The one in question is an MPA full size 9mm.
It's marked with the maker, city & state, caliber and serial number.....but has no model name/number information anywhere on it.

When doing the form 1, it's giving me a list in a drop-down menu of about 30 various models people must have previously input, how do I know which one is mine? Or should I use "N/A" since technically it's not marked with any model. I've read about the ATF asking for picture of markings lately, I'm not sure what I can show them besides the caliber, maker, and serial number. I don't have the original box so I can't check that. Anyone have advice on how to proceed? Would like to avoid a rejection if possible.

I would imagine the manufacturer would have the info if you email them the serial? Mpa customer service?
I’d start there if it was mine.

My understanding is that the model designation is optional. Go to https://www.atf.gov/firearms/firear...rms-ammunition-firearms-verification-overview halfway down the page.

"Model Designation (if assigned)"

Since you are the "Maker" you could add a model designation if you chose and mark the firearm as such. Otherwise I would think that you could leave it blank. The original manufacturer did.

It is certainly your money, your choice, between the trigger slap and poor ergonomics, a semi auto Mac style pistol would be about the last firearms that I would consider spending $200 to add a stock to. I would think a firearm that was designed to be a SBR with good ergonomics would be my choice. Good luck with the project.

Thanks.

I have several SBR's already, MP5K, AKS74U, AR, UZI etc just felt like throwing a stock on one of my multiple MAC type guns. Just for funsies.

I sent an email to the manufacturer, maybe they can clear it up. I'd think plenty of people have SBR'd these over the years, I'm sure it can be done just don't want to have to file multiple times to get it right.

Something to think about, to buy my first machinegun, I sold most of my semi auto collection to raise the cash. If you have many guns, have you ever thought to sell most of them to buy a machinegun? I missed some of the semi autos. But I would do it again. Just a thought.
