What other markings are on it? Does it have "Made in the Czech Republic" on the receiver? If the receiver is US built, could be something like ORF or Century made rebranded. The only two companies making Czech rifles is CZ-UB, who only offers the military select fire version to LE/governments, and Czech Small Arms, who imports through Czechpoint. CSA also used to be D-Technik, which is the other makers mark you will find.
In short - did it look like this? This is a Czechpoint rifle imported from D-Technik prior to the factory's name change, came to me a little over 4 years ago.
This is the current Czechpoint importer stamp,
Does this help?
