Old news, but good on them anyway. However, they aren't a "major" player in the firearms industry. Not like Glock, or Smith & Wesson anyway. The two of them, along with another company, who I can't remember at the moment, all sent letters to CA citing the uselessness and cost and unproven method of microstamping. So far, that is talking the talk, but when the $ is laid out, people usually take the dollar.
Barrett's move has been ballsy and has been applauded, but they, like STI, are still a "specialty" kind of market on firearms to the LE field.
I'd like to see a major company step up and refuse sales and service to CA.
