About to purchase, need advise

[DocD]

I am about to purchase a CZ 455, (I am in CA so some of you know what I am up against) I called the local dealer and told them I was interested in a CZ 455 super match or Ultra Match, he responded with only having access to the Super Lug model, my question is, What is the difference?, I look on the CZ web site and it would appear that the Super or Ultra have a different barrel, but the way it is written it is a little confusing, Would anyone here know? also is there a preference of a metal Mag. over the plastic one. Thanks

Super Match has a 20.5" 12 groove barrel with a Beech stock and LPA style sights. Ultra Match has a 24.8 in 12 groove barrel, Beech stock, and the tangent style sights.

Bud's has both in stock, and will ship to Cali, I believe.

Super Lug?

The CZ plastic mags are fine. Metal are good too. Guess which will rust?
