It depends...
Since I too live in CA I feel your pain. But, the answer depends on money, purpose, calibre preference, poser value, etc, etc...
.223- Mini 14 is expensive . Saiga has a 10 round .223 semi at about $290.00. The SKS is an acceptable option, but price/demand is rising. A company called FabTen is making a 10 round fixed mag AR clone.
308/30.06- Garand. If you really gotta have a detachable mag, SOCOM.
Since I mentioned the Garand, I want to put in a good word for military surplus weapons. They are battle proven, reliable and less expensive than other current offerings. Take a look at some of the websites, they may meet your criteria.
