I am also in CA, if that matters with what I can and cannot have in this silly state.
Buy the upper already assembled.
The lower requires a set of brass punches, rawhide/wood/brass hammer, and the rest you should have in yer collection.
There are a couple springs that can be quite pesky to get put in. Make sure yer in a 'controlled area'. They can be a b*tch to find when they launch back at ya.
A couple tries, and you'll get it.
