I've just seen them on their web page when I was on there buying AK stuff. I don't know of anyone that has built a FAL on one though. I've built on two DCI receivers though and they are jut like their stamped AK rec.s.....Top Notch.
I just finished a build on one of the Century receivers. No problems and it shoots great. It's being Parked and Duracoated now. Will post pics as soon as I get it back.
