Is their a difference in the 452-2E Super Lux and those marked 352 Ultra Lux? GW
I have never seen a CS rifle with any of those actual markings on the rifle itself.
A lot of confused dealers try to claim such.
The boxes may be marked "Ultralux" on the box end flap, but the receivers are marked with the normal CZ-452-E markings.
The barrels either have "Super Exclusive" marked on the top or "Super Brno 2500". I have owned 2 or 3 of each over the last 20 years.
