These things used to be great. But once they started topping $600 a rifle, the party was over. When I bought my C it was $627.63 after tax. That's just the rifle.
On KTOG I hear of guys who spent less than $500 for a used, under $550 for a NEW.
Once you figure in the cost of a scope and rings, and ammo (DEAR GOD .223 WON'T GO DOWN), and the muzzle brake, and the ammo, and the extra magazines, and the ammo your spending that $1000 and when you finally get it to the range you realize that you really just should have spent that money on a DPMS AR-10 clone. With an Adams Arms gas piston. With extra magazines and ammo.
.308 is actually cheaper in my area that Remington .223. I never thought I'd see the day.
ALL that being said, sometimes you'll get lucky. One shop here in KC has a used CA on the shelf for $479.99. After tax your looking under $550. That's the way it should be. If you can find one of these at pre-panic pricing you'll probably love it. Until you buy ammo that is.
