hello
i have a cz 712 12 ga with 26 in barrel
i have not shot it yet but i disassembled it to clean it and oil the internals very well built gun and the price is great too i got mine under $300
the best advice as far as info goes on these guns is to check out czforum.com and go to thier rifle and shotgun forum plenty of info there looks like the cz will be a keeper i believe they are made by huglu out of turkey
armsco is the main supplier of parts from what ive gathered
i bought a set of carlson sporting clays chokes for mine due to the fact that everyone who has used them says they improved their score eminsly on trap and skeet
good luck hope this helps
