The test of their laws with regards to the intent of the 2A would be how hard it is to buy a battle rifle and other weapons suitable for militia duty. What’s that like in CA?
I think the M1A is still legal. ARs and AKs have all been banned, with all older guns on registration lists for future confiscation. SKSs also registered for future confiscation.
I still remember when people were honest/stupid enough to register their SKSs only to have them confiscated. The attorney general said it was OK to register the guns after the deadline had passed, then the court said it wasn’t OK, so all those guns were illegal and were subject to confiscation.
Welcome to the People’s Democratic Republic of California where the legal possession and use of a piece of metal and wood can make you a felon. Every single one of these SKSs was purchased legally but only later made subject to registration and then confisction.
