80% AR15 RAW LOWER - OPTIONAL ENGRAVINGS
RTB is now offering raw 80% lower receivers pre-engraved with whatever serial number and manufacturer information you want. We typically engrave to a depth of .01" and you will need to fill out the following information in the text boxes above:

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. If you add the same lower multiple times, we will continue the serial number sequence for you.). **DEFAULT PREFIX = "S/N:"
