PRK native here. Rifle choices are limited.
Mattd, if one has an AR-15 or clone, it can only be sod out-of-state. True M-16's, being full-auto and therefore Class III, are straight-up ILLEGAL TO POSESS IN THIS STATE. The PRK banned all machine guns a few years ago.
Want a pistol grip? Sorry. No pistol grip on a rifle UNLESS IT HAS A FIXED MAGAZINE.
That'd be things like the AR-clones that have no magazine well, and only hold 10 rounds, or that butchered FAL monstrosity.
Switch-mag guns you CAN buy are as follows. I THINK I have 'em all.
Mini-14's, and -30's.
Ruger PC carbines.
M-14-alikes, like the Springfield M1-A.
Remington 7400's.
Browning BAR's.
Winchester M-100's.
Garands, and M-1 carbines.
Remington M-8 or M-81 Woodsmasters.
H&K SL-6's and -7's.
That Kel-Tec rifle shown above oughta qualify. It was made with the PRK market in mind, and for that reason lacks a pistol grip.
SKS's are ok, provided they have the original FIXED magazine.
MAS 49/56's.
FN-49's.
The Ljungman, and it's Egyptian copy, the Hakim.
Unfortunately, despite their LACK of a pistol grip, all Saiga rifles and shotguns are defined as assault weapons by virtue of being an "AK action", courtesy of a ruling by the CalDOJ. Truly stupid.
Paraphrased, the assault weapon ban includes "any semi-auto rifle with interchangeable magazines that has any TWO of the following: a pistol grip or thumbhole stock, (No CX-4's, sorry.) a threaded barrel, a flash hider, a bayonet lug, or provision for a grenade launcher."
Basically, that'd be any semi-auto with swithchable mags that looks slightly scary or is of modern military origin. MAS 49/56's are hard to find because they come with a built-in grenade launching rig, and have a muzzle break that many folks assume is a flash hider. Last time I looked, though, DOJ didn't have 'em listed. However, distributors won't ship 'em here because they're not sure, and don't want to get in trouble. I think they're still transferable within the state, though, unlike any of the rest of the "assault weapons".
You want a semi-auto in this state, it'd better be plain-vanilla-hunting-rifle-looking thing. M-14's and Mini-14's are about the closest thing to a real rifle left available here, but M-14's are a long way from cheap.
Pricewise, the best bets are the Remington 7400's, the Mini-14's, and the pistol-caliber Ruger PC carbines. They all run about $400-ish. U.S M-1 carbines can be had in this range too, if it's not a collectable one. Remington M-8/81's can be had for this price or even less, but they're 5-round fixed-mag guns that went out of production in the '40's, and are only available in two fairly obscure-but-good calibers, .300 Savage and .35 Remington. They also can be found in 3-4 totally obsolete calibers that you can't get ammo for at all, but that's niether here-nor-there.
SKS's are VERY inexpensive for what they are, and deserve a close look.
Unless it's a beat-up old military surplus gun, all of the rest will START at about $600, and go up. The BAR is about the best of the lot if you're considering a new gun, and has the added bonus of being available in Magnum calibers.
Dunno how much the Kel-Tec runs. If it's reasonable, it's probably worth a closer look also.
If the butchered FAL is really running $1700, that's about 3 times what it's worth. FAL sporters used to sell here for about $500. $1700 is robbery of a captive audience, as I doubt those things are competition-grade match guns. (I could be wrong about that, though. Maybe that's who their target market is. I dunno.)
This state has really stupid laws.
