Pull the firing pin, replace with an aftermarket unmarked one, or place the tip in a piece of fine emory cloth or board, give it a few spins and Voala! The microstamp is gone.
Valve lapping compound also works well.
Fixed
I’m waiting for the inevitable “aftermarket” micro-engraved pins that stamp tiny smiley faces on the primers. Or maybe some other text. I was thinking “Property of BATFE” might be entertaining.
They understand that. The bill text states:
6. (A) Any person who wilfully defaces any machine-gun, large capacity ammunition feeding device or firearm, INCLUDING DEFACING A MICROSTAMPING COMPONENT OR MECHANISM OF A SEMIAUTOMATIC PISTOL AS DESCRIBED IN SUBDI- VISION TWENTY-FIVE OF SECTION 265.00 OF THIS ARTICLE, is guilty of a class D felony.So if the police find you in possession of a firearm whose serial number indicates that it was manufactured after the date of the bill, and where the microstamping feature is disabled, then they charge you with a felony for each firearm. You can be sure that the police will use any opportunity they can think of to inspect your guns for such a violation.
