No doubt many of you have received an email from gunbroker.com about this device.
California DOJ has been willing in the past to provide a written ruling on these things, as they did with the bullet button. We'll see if they'll cooperate again. What I find so amusing to watch is politicians who agonize over a ban and finally jam it through, and then enterprising companies invest a way to mostly avoid the ban. It has to be frustrating for them :-)
I don't see anything here that says it's a permanent change, nor does the CA law require that. There is only this 1 year window to register and, if modified to not fall into their assault weapon category, it cannot be un-modified later.
