cookekdjr: it's truer than you think
I actually saw a man come into a shop in Yucca Valley and look over a NEF single-shot rifle just like you show (but with Tasco scope). He then asked the owner's husband "can I get high-cap mags for this"?
The owner scowled and said "no", and then just sat there. I kept waiting for him to explain, but he never did.
So, I walked up to the guy, explained how a break-action doesn't take magazines at all, regardless of capacity. Showed him how to work the action, etc. Wrote "www.thehighroad.org" on the back of the store's business card. He ended up deciding that it was a pretty cool rifle at a good price, and that he was okay with single shot, so he bought it. Still ticks me off that the owner wouldn't take ten seconds to explain the rifle to an obvious newbie, so I'm quite glad that they're turning the business over to their son this year.
Above pic is SU-16C, the CA variant is the same but with a fixed stock. Note improved sights, front sight post over gastube for stability, case-deflecting charging handle, etc.
Oh, and getting back to topic: SU-16CA seems to be what you're looking for. If cash is short, then an SKS ($200 and under) or M1 Garand through CMP (approx $340). Not that those last two resemble an M16, but since you mentioned CA FALs, I suppose you might be open to anything militaristic. Cheers, -MV
