Engraving Service for your Mail In 80 percent lower

Please note: You cannot send us an 80% lower if it has been machined or modified in any way.

RTB is now offering engraving services on mail in 80% lower receivers. We always recommend engraving a serial number and/or other identifying information on 80 percent lower receivers. The engraving will be much deeper than the ATF required .003" depth. We typically engrave to a depth of .01"

You can have any of the 5 lines below engraved. Pick and choose if you like, but we recommend using all of them. We recommend using all capital letters, but we will engrave exactly what you type.

1. Name of Person or Entity (This can be your personal name, trust name, etc.)

2. City & State

3. Model (This can be whatever you want) **DEFAULT PREFIX = "MOD:"

    4. Caliber ("MULTI" is a good choice but you can choose whatever caliber you want) **DEFAULT PREFIX = "CAL:"

      5. Serial Number (This should be unique and should not match any of the serial numbers that you currently own or have manufactured). **DEFAULT PREFIX = "S/N:"


      Standard AR Frames: See product photo for engraving locations of all 5 lines

      Safety Engraving: Both sides of the receiver will be engraved if a safety option is selected.

      Polymer 80 Pistol Frames: 15 character limit. We are only able to engrave your Polymer 80 Pistol frame if it comes with the small metal plate installed. We can only fit 3 lines on that metal plate. Choose as you see fit, but we recommend lines 1, 2 & 5.

      Polymer Lower Frames: We are only able to engrave 1 line on the small metal plate. We cannot engrave the polymer portion. We recommend having the serial number engraved

      Magwell Art: We recommend deep magwell engraving on raw lowers and surface magwell engraving on lowers that are already coated or anodized. Click on the refernce chart tabs above to see examples.

      Make sure the receiver or frame is completely stripped.

      Turnaround time is typically 7-10 business days once received. We will email you further instructions once the order is placed. You will also see the same instructions on the order confirmation page after the order is placed.

      5 of 5 Awesome Job RTB! and Great Service! July 27, 2020
      Reviewer: Bobby Peters from Mobile, AL United States  
      I recently mailed in two lowers for engraving. They arrived last Wednesday, and the same day the staff were working on them. There was a concern over the chosen mag well art and fire/safe logos, due to the design of the lower, Dakota called me and discussed my options and we got it worked out. He was very helpful, and had them done and mailed back to me the next day! I just got them today... I am very pleased! They look awesome! I will deffinitely buy from RTB again.

      5 of 5 Awesome July 10, 2020
      Reviewer: JD from Joliet Il  
      I was waiting for the RTB receivers for engraving to be back in stock for weeks. I couldn't wait any longer because it was going to be a gift for my nephew graduating USMC OCS. I mailed my receiver in on a Wednesday, Friday was a holiday. I still had it back in my hands on the next Thursday. Amazing looks, amazing turn around service. Don't hesitate if you're worried about long wait time or quality.
