Semi Auto Carbine ATF Approval

it is required when you make an sbr/silencer on a form 1

Exactly, which is what I was saying before. If you are making a "Firearm" under the definitions of Title II of the NFA (Silencer, SBR, SBS, AOW, destructive device, Machine Gun...theoretically ) then you have to mark it per that section of the code.

If you're making a "Title I" firearm (as covered by GCA'68), then there is no law that says you must do so.

it is required when you make an sbr/silencer on a form 1

The OP is not looking to make a SBR or a silencer based on his initial post, so the "Required marking" on a Form 1 does not apply in this case. The ATF language on a home built firearm states that it "Should" be marked if it is subsequently sold.

My advise has be and will remain to be "Contact the ATF Technical Branch in writing should you have any questions on this project and ask for a written response"

Having a letter from the ATF Technical Branch that details your question and what their position is sure as heck beats any advise or answers (Right and Wrong) provided on an internet chat forum.

It's perfectly legal for you to build a firearm of your own design. The gun you build doesn't even need a serial number or any kind of markings of who made it. However if you do build your own firearm it must remain in your custody, so you can't sell it or transfer it to anyone, that's when you need a manufacturers license.

If he decides to sell it, it then needs a serial number but he doesn't need a license unless he's building with the intent of selling.

It does NOT need a serial number, as long as it's not an NFA weapon. The ATF merely suggests that you put one on a home made firearm.

Make it to accept Glock 33 round mags!!

That's the plan!

 

[kcshooter]

So you're making a AK/Grease gun with a H&K stock that takes Glock mags?

he doesn't need a license unless he's building with the intent of selling.

Get a license. I'm buying.

Thats already been established, but it keeps being rehashed with irrelevant info like a Form 1, SBR, silencer, manufacturing FFL req.

If this is to be a prototype for possible production, markings, though only suggested by ATF and not required, may actually be a good idea.

Again, ATF Technical Branch is a Valuable source for information that will keep you on the right side of the laws in most cases.

And people keep ignoring it, so it has to be reasserted. Whether the OP wants to put a serial number on the gun is his business. He asked what he needs.

When I finish the dimensioned blueprints I'll send it in and see what they have to say. Better safe than sorry. Any idea how long it takes to hear back from 'em?

I've had varied response times with correspondence from the ATF ranging from a few weeks to over 7 months. Your experience may vary.

Keep in mind that a home-built firearm for your personal use and a prototype for possible production may look to some to be identical, but one has an implied intent for resale and the other does not. The path from prototype to production is long and very expensive. If your serious about it, do your research and due dilligence and take your time. A short-cut in the front end can cost you huge in the long run.

you (might) also have to submit the plans and a functioning copy to tech branch for approval.

also,check local state regs about possessing a firearm w/out serial number etc

There are plenty of unserialed firearms in circulation. S/N not required on commercial firearms until GCA68, however most manufacurers numbered them anyway.

Most laws would pertain to altered, removed, or obliteratied serial markings, not the lack of them.
