CTAC is mostly clones as far as I know. They aren't bad guns if you get one of their AR's (Which are decent VFC clones) I had a M16A3 by them and that thing was pretty damm good for the price I paid for it. Not top notch but still damm good for the money mine was used and abused a fair bit and it never quit on me once. Traded it and I regret ever getting rid of it.
That being said I saw one of their snipers and wasn't to impressed by it.
