I have two CZ uppers for sale. One is new in the package, unfired. I only took it out of the bag to take a photo of it. It comes with one ten round mag. Asking $280 OBO. The second one has been fired 400-500 rounds and works great with all ammo I tryed, it works best with HV ammo. It is in excellent condition and very accurate. It comes with a pic rail attached to the bottom of the hand guard, and has a YHM folding front sight, and a folding rear sight, although I cannot remember the brand. It also has two ten round mags included. That one I am asking $300 OBO. If you have any question just let me know.
