80% ar build question

[norcrawler]

just ran across this post from 2008. just wondering if anyone can confirm this is true.

Having a serial number and make/model/manufacturer/city/state markings are what keep you from having to spend 20K in legal fees to prove that you don't have a 'Zip Gun' or didn't 'obliterate' a comercially manufactured firearms markings.

CYA on this

i was planning on getting it engraved (tomorrow possibly) and was just going to do a serial (first, middle and last initial. followed by the last 4 of my social) thats just what ive seen and seems like a pretty full proof way to prove its yours incase of any leo encounters.. would it be highly advisable to put make/model/man./city and state on there aswell?

Zip gun only applies to building a gun that is not a clone of an existing gun. Look up the legal definition of a zip gun.

Only reason you would want a serial number is if you are planning to sell it in the future.

IMO...
If are going to engrave it with a serial number, do it so that it conforms with Federal laws/regulations.

So, the engravings need to have a minimum depth of .003 inch and in a print size no smaller than 1/16 inch and would need to include:
1. Manufacturer's name
2. City & State the firearm was manufactured in
3. Firearm's model
4. Firearm's caliber
5. Firearm's serial number

You could have a problem with them for spitting on the floor.

The law doesn't require you to put on a serial number.

Would I do it? Yes.

If you're gonna do it follow Quiet's instructions.
