I reckon you could say I'm getting hooked on CZ firearms since I own 4 CZ pistols. ( A CZ-75, CZ-40 and a pair of CZ -83s ). Now I've got a CZ 527 in 7.62x39 on the way, should he here this week. A question about scope rings, I've ordered a set of Millet CZ 527 rings for this rifle, what about bases ? Is the receiver made to accept just the rings or are bases necessary. I've not seen bases listed for this rifle and I have to plead my ignorance as I've not had one of these rifles in hand to examine it. Any help and advice is greatly appreciated.
