From I've read about the Golani Sporter Galil's from Century, if I were to purchase one, my best bet would be to look for the receiver with the serial prefix of "GLN"? I believe that these are Caspian receivers. Is there anything else that I should take into consideration and look for? I've wanted one for quite a while, but I have heard so many negative things about the CIA, Inc. Golani Sporters. Thanks!
