Is it an offense to remove the SN from a barrel and slide attached to an 80% lower?

BRB, Gotta call a friend in Seattle to find out about carrying a knife in Texas. I have a KBar and was wondering..........LOL!

Humble brag way to say you don’t own a Glock

I've never considered a Glock, I wouldn't ever own one. Not because it's a Glock, they just don't feel good in my hands.

Ruger MKI/II/III/IV have the SN on the upper portion with the barrrel. The lower grip (with FCG) is not serialized.

Because on the Ruger, the upper is considered the actual firearm. Don’t know why.

Must have been an AK build.

They're on my HKs also.
That is off the top of my head.

CZs also. On the other hand my Makarov only on the frame.

I noticed it on my Ruger Mk III years ago. Thought it was a bit odd.

Is it an offense, however, to remove the SN on the slide and barrel when they're attached to an 80% lower which was never serialized to begin with?

For ATF purposes, only the frame/lower would be considered a firearm, right?

Would removing the SN from the slide and barrel constitute altering a "firearm" in this context?

Both Title 35 and 18 USC seem to define firearm as a weapon, but only the lowers are actually regulated.

Anyone know of a similar case in Texas?

SN on receiver is all that matters via Federal law.

Hence why it is legal to put an aftermarket BBL on a Glock or other similar handgun.

Why would someone in Indiana ask people in Texas this question? You need to ask attorneys in YOUR state and ask ATF.

ABSOLUTE correct answer, also in some firearms, the upper is the controlled serialized portion (FN FAL example)

With serials ground off, I think the rifling should be checked against a database. I could care less about the grinding. But thieves do that sort of thing to stolen guns. And I believe in busting thieves at every opportunity.

Springfield XD/XDM/XDS pistols are all matched serialized on the frame, slide and barrel.

Could it be a non-unique part/model/run number? Regardless, if the receiver is not serialized, the barrel number is irrelevant. Next time buy unserialized parts.

Sometimes, barrels or slides having a matching serial number is about the gun being matched during assembly so that parts are known which goes with which gun frame.
