Just want to check, is it okay to engrave on the trigger guard when it is part of the receiver? Example the billet lowers that are made with integral trigger guards.
Secondly the letters engraved must be no smaller than 1/16" or 4.5 font? |

Integral trigger guards are part of the receiver, so as long as it meets the "conspicuously placed" requirement you're good to go.
No depth requirement, just the 1/16" minimum...which is just under 1.6mm. ETA: brain fart...I typed the opposite of what I intended. As mentioned, the only requirement that applies to all of the identification markings is the .003" minimum depth. The Serial Number is the only piece of info that has the 1/16" minimum height requirement, which is just under 1.6mm. |

No depth requirement, just the 1/16" minimum...which is just under 1.6mm. There is a .003" depth requirement for the serial number, which is not very deep. I have been engraving deeper to allow for refinishing later on. "The engraving must be able to be read without enhancement" is the word I got from ATF.

Absolute complete brain fart on my end, and I posted the exact opposite of what I was thinking. Everybody always assumes the height requirement is for all engraving, when reality is it's just for the S/N. Everything else is indeed just the .003" minimum depth. I'll correct my original post.

Quoted:"The engraving must be able to be read without enhancement" is the word I got from ATF. The way I look at it, they actually state for SN must be no smaller than 1/16" in size, so I'm guessing that can be read without enhancement, since that is what they require. To all I knew the depth had to be minimum 0.003" So here is my other issue finding someone that can engrave "font size 5 or 5.5" and get the 0.003 depth, I know most laser engravers will not meet the depth requirements. I'm sure it can be done since they engrave things that can't be seen with the naked eye

I knew they always input height in mm/inches, so you may just have to provide that info. Can't remember if there was a way to input Font size 5 or not. And the size will vary based on actual font. Depending on what the font it, the letters may be a different size than the numerals. |

The main thing about "without enhancement" is if the receiver is painted or otherwise refinished later. You can't fill in the engraving with paint such that you can't read it and/or it is not at least .003" deep. I doubt that even color filling the engraving would pass muster unless the color fill still leaves at least .003" depth. |
