It looks like they're shooting it all the way out to 15 feet. I'd like to see what it does just a bit further.

The big thing with building a CETME/HK style rifle is placement roller recesses inside the trunion. Century in the past has built them where there was absolutely no allowances for wear. I'd want to check that before I bought something like that. But I just saw one for sale on Atlantic Firearms for $629.00, that's a hell of a price; especially if it turns out to be any good.
