Looking for ideas on where to engrave and if a laser would work? I know they will for aluminum receivers, but wasn’t sure about steel.
Crazy idea, but could you engrave inside the receiver opposite the ejection port, so you would only see it when you opened the bolt?
Probably not good to mess with the surface the bolt is riding on is my initial thought.

Anyone want to show what they did?

Protip.
You'll not care after you shoot it and enjoy it. Pick a spot engrave it.

Yeah I'm with this guy.

Stick it under your top rail.

Nobody's ever going to check for it anyways.

i sbr'd a r700 receiver and just had it engraved at the back of the receiver on the same side that remington marks , it blends in fine

pretty much what everyone has said though , once your through the building stage and into the shooting stage you won't care where it is

To answer the other part of the question.... Yes, a fiber laser will work for steel as well as aluminum.

Good points, I’ll stop worrying about it.

Could always engrave the barrel, too...I mean, if you ever swap out the barrel, you'll probably be swapping in a longer barrel, no? And if not, you can always just engrave the new barrel too...

The barrel is no longer an approved area for engraving. The rule changed in the last year or two. In this thread.

Lot of people just do the barrel. If the receiver has room I'd just do that and not worry about it.

If done prior to August 2022, that would be fine, but it's no longer a compliant location.  It must now be on the frame/receiver.

I saw someone else mention that a while back you got a link to the breakdown?

The CFR was amended.

By engraving, casting, stamping (impressing), or otherwise conspicuously placing or causing to be engraved, cast, stamped (impressed) or placed on the frame or receiver, or barrel or pistol slide (if applicable) thereof certain additional information.
