Century Arms has a spotted history when it comes to the assembly of rifles in-house. In my opinion, their previous CETME attempts have been dubious at best. I had a CAI CETME in the past and it was a piece of junk, to put it lightly.
When Century released the C308, which is a hybrid of CETME and G3 parts, with supposed collaboration with PTR, I decided to give them another chance. I'm glad I did.
