To help our customer in states with stricter gun laws (California) we offer you the ability to purchase your 80% lower receiver with your own DOJ assigned serial number engraved onto it.

We use a laser engraver to precision engrave text to the required depth of 0.003 inches to meet the ATF’s specification for serial number marking as well as California law.

California is currently the only state that we know of in which a serial number is required.

To meet the ATF serial number requirements, the following information must appear on the lower receiver :

Serial Number: You will need to have a unique DOJ assigned serial number for each firearm per ATF ruling.

Caliber: We will mark your receiver with “Cal: Multi”. Please reference photos to see an example.

Manufacturer’s name: Enter the name of the builder who will be completing the lower receiver. You cannot exceed 30 text characters; this includes any spaces. It is best to use your full first and last name.

Manufacturer’s city and state: Enter the city and state of which the manufacturer resides. Please use a 2 letter state abbreviation. Please do not exceed 30 characters here as well.

To be fully compliant with AB-857, you must complete your engraved lower PRIOR TO JULY 1, 2018 if you would like to keep your lower unregistered. If you fail to engrave OR complete your lower before July 1, 2018, you will be required to register your 80% lower with the CA DOJ.  If you finish an 80% lower and don’t engrave a DOJ issued serial number after July 2018, it is considered a misdemeanor.

(This engraving service is not for registering “assault weapons”. California “assault weapons” must be engraved with a serial number provided by the CA DOJ)

Serialized lowers will require a signature upon delivery, this is non-negotiable. We do not want the serialized lowers to be stolen and by requiring a signature, we will be minimizing this risk as well as keeping your information safer in case of a stolen lower receiver in transit.

Once your order is submitted to us we are not able to edit or cancel your order. Please ensure that the information you supply to us is correct before submitting your order.

    Serialized 80% Lowers

    LOOKS GREAT, I COULDN'T BE MORE PLEASED I bought 2 and plan to buy several more.


    Easy build

    Sad that California residents rights are restricted. But this is a great product to still build and enjoy an AR style rifle.


    Good to go.

    This is my first build and I learned a lot. Everything worked out right my only problems were with the new router I picked up because my old one did not fit the end mill.
