I lived in CA and owned a Semi Automatic version of the AK-47.
They passed an Unconstitutional Law and I was forced to Register the Rifle, putting my name on a list of potential Domestic Terrorists. Not doing so would have made me an Overnight Felon.
I ended up selling the AK to an out of State Buyer and made a tidy profit as a result which helped fund my next purchase, a “CA Legal” version of a Semi Automatic AR-15.
In order to be “legal” in CA, the Barrel end was not threaded, there was nowhere to mount a Bayonet and a “tool” was required to release the Magazine which could only hold ten rounds of ammunition.
An innovative solution to overcome the Magazine release “tool” requirement was called Bullet Button. It was a recessed button release that could only be pushed in using the tip of a Bullet or any other pointed implement, AKA “tool”. With practice, changing out the Magazine took about five seconds.
The Politicians in Sacramento were horrified about that and went to work. Sure enough, Rifles equipped woth a Bullet Button were reclassified Assault Weapons requiring Registration. Uh oh, I was an Overnight Felon once again.
This time around I ignored them and we eventually moved to a Free State. Since that time, my Arsenal has substantially increased in size.
I still have to fill out that dreaded 4473 Form when purchasing a new Firearm, but I know that if I falsify it I can always use the Hunter Biden did it defense in Court. Just kidding...
