NOTE: Applying a serial number your 80% lower is not required in any state, except for California when AB 857 takes effect on July 1, 2018. Residents outside of California may wish to utilize this service for the event a firearm is lost or stolen. Again, serial number engraving is optional for residents outside California.

For California Residents: On July 1, 2018, California AB 857 will go into effect, requiring homemade firearms to be marked per the ATF's minimum requirements for firearm identification. Failure to mark home-built 80 percent lowers by July 1, 2018 will force those who wish to comply, to apply to the state Department of Justice for a serial number, thereby registering the serial number and firearm. Buy your engraved 80% Lowers Pre-Engraved now, before AB 857 takes effect.
