Product details

This product is for existing AR15 or 308 lowers shipped to us for custom serial number engraving.  You are able to ship your lower to us, and we can serialize it.  You can send us either 80% lowers or finished "100%" lower receivers for engraving. We have an FFL license. As of 2018, all 80% lowers in California must have a serial number engraved.

We use a powerful laser to precision engrave text to a depth greater than 0.003 inches as required by ATF's specification for serial number marking and California law. To meet ATF serial number requirements, the following information must appear:

  1. Serial Number: Enter your desired serial number in this box. We recommend using less than 12 characters of text. You can use letters, numbers, or combination of both. ATF requires serial numbers to be unique for each firearm you serialize. SN: Will be engraved before each serial number.  
  2. Caliber: We will mark your receiver with “Cal: Multi” as shown in photos.
  3. Manufacturer’s name: Enter the name of the person who will complete the lower. Maximum of 30 characters of text including spaces. We will have to split it into two lines of text if you exceed 14 characters.
  4. Manufacturer’s city and state: Enter city and state of residence for the person who will complete the lower. Use 2 letter state abbreviation. Maximum 30 characters of text including spaces and commas. Anything exceeding 14 characters long will be split into two lines of text.

Model number is not required to be engraved.

While we will engrave Polymer AR15 and 308 frames, please make sure you are reading the full laws on AB 857.  In order to properly manufacture or assemble a Polymer lower, you must embed 3.7oz of steel into the frame to be compliant in 2018.  You can read more about this with Assembly Bill No. 857.  

We do not report serial numbers or any other customer information to the government. By engraving a serial number, you are not registering your firearm.

Please verify the information you supply to us is correct before submitting your order. All lowers will be engraved in upper case letters. Custom engraved receivers are not returnable, and orders cannot be canceled once engraving is completed.

Mail Receivers to:

80 Percent Arms Inc.
3480 W Warner Ave, Suite L
Santa Ana, CA 92704

We suggest using shipping insurance with signature delivery. We are not responsible for receivers lost in the mail. Please make sure to include a copy of your receipt for your engraving order in the box with your lower receiver. A $7.99 shipping charge will be added to your order at checkout if your order is under $200. This charge covers our cost to ship the lower receiver back to you. 

All lowers must be 100% stripped of any parts in order to engrave.  There are no exceptions to this rule.  

Lead time: Turnaround time is currently less than 1 week.
