I also live in California, so I share your frustration. If you want a semi-automatic .223, the only option I can think of is a Ruger Mini-14 or Ranch Rifle. I recently bought a Stainless Ranch Rifle with a black plastic stock. If you want a handy and reliable rifle with an evil, "assault rifle" look in California - this is about as good as it gets. The blued finish is probably more military, but I like the look and durability of stainless. The Minis have a mediocre reputation for accuracy, but otherwise are nice little rifles. They cost around $450-$550.
Other options to consider, if you aren't stuck on .223 are:
- Mini-30 (Same as Mini-14, but in 7.62x39 caliber. This makes a lot of sense to me, since the Mini-14/30 rifles aren't especially accurate anyway, so why get the high-velocity .223. The 7.62x39 probably penetrates better and could be legally used for deer hunting if you wanted to). Around $450-$550.
- M1 Caribine. This is significantly lower powered than the above options. Nice, handy, historic (WWII and Korea), low-recoil rifles. There are lots of surplus magazines available for low cost in other states, but for a Californian, you'd be limited to 10-round magazines - I don't know how common they are. Around $450-$600.
- M1 Garand. This is a lot more powerful than the other rifles mentioned (it shoots the 30/06). It was the standard WWII U.S. rifle. Larger, longer, and heavier than the others. Uses 8-round "clips" that you insert from the top into a fixed magazine. About $500-$800.
- Springfield Armory M1A (various configurations). This is similar to the Garand, but shoots the .308 (just slightly less powerful than the Garand). It is similar to the Garand, but uses detachable box magazines. Original 20-round GI magazines are expensive and illegal in California. I'm not sure what 10-round mags go for. These are also expensive rifles. Around $1,200, depending on configuration.
- SKS. These are surplus rifles from former/current communist countries (Russia, China, Romania, etc.). They vary in price from around $400 (for a pristine Russian) to around $150 for a well-used Romanian. I ordered a nice one from G-U Wholesale a few months ago for $129.95 plus shipping and FFL fee. It was in very good shape - if you have a dealer you can order through, I'd give them a call. They shoot the same cartridge as the Mini-30.
- There are some FAL rifles avaiable that have their magazines permanently attached to make them legal. It is frustrating not to be able to use detachable magazines, but these rifles probably shoot fine and would certainly have the look and feel of a full-blown assault rifle. They also shoot the .308 (no doubt someone will point out that they really use the 7.62 NATO - which is virtually the same thing).
Maybe someone else will be able to think of some other options (l'll be intersted myself). Good luck. I'd get a Mini-14 or 30 AND and SKS.
