I believe "engraving" on a plastic lower would create stress risers at every cut.......Then it could/would break in pieces if dropped or introduced to sudden shock...........

We are talking about .003". That's not going to make a measurable difference in the stress.

Additionally, engraving requirements do not specify "where". On the 15-22, they could, for instance, probably be put on the buffer tube, since it is part of the lower (unlike an AR-15 where it could be removed).

Alternate places would include the trigger area and front of magwell.

Laser engraving is common for plastic parts.

I simply did a google search for, "nfa engraving <mycity>" and got multiple hits. One is 2 blocks from my workplace.

You could also check with whoever in your area is the "go to" FFL / SOT dealer. They will know who is the best local on engraving, barrel cutting / threading etc.

I used Tar Heel State Firearms. They engraved two lowers for me (metal).

Not to be a smart *** here but.... Doesn't the lower already have engraving from the factory? Or is that somehow molded in so cleanly

There are several reasons why someone might want to, or in some cases, NEED TO, have the lower engraved.

If one wanted to convert their rifle, for instance, into a Short Barrel Rifle (SBR), then part of the requirement is the firearm be engraved with the Maker's mark. S&W engraved the lower and 'Made' a Rifle. However, the owner would 'Make' an SBR.

Orion Arms has a lengthy and detailed web page about engraving SBRs. Even if you do not use their services, it provides useful information. And they do engrave plastic lowers. I had a plastic lower on a Kel-Tek PLR-16 converted to an AOW engraved locally.

Rhetorical Question:
If permitting is applied for to make a SBR isn't the serial number of the weapon to be converted required in the paperwork? Why would additional disfiguration of the receiver of the converted weapon be required when it already easily identifiable? This seems like a stupid wasted step to me.

Exactly. Just like putting unnecessary importer markings on guns. They serve absolutely no useful purpose. They simply degrade the firearm.

The serial number of a firearm is not REQUIRED to be unique. There is no law for it to be so.

There are several places where you can have a lower receiver engraved with a custom serial number (direct from the manufacture, or with an 80% lower - which does not require a serial number and other markings until/unless it is sold).

Just providing a perspective as to WHY it might be necessary. Not advocating that it is useful.
