Guns, Dogs and Blades QnA

I've looked at a held a Sub 2000 a few years ago and it was interesting and has potential. The folding method negates the use of a mounted optic though, doesn't it? Not that it is a hard requirement, I'd prefer to have a red dot of some sort.

I have not used this, but I may at some point.

Skip to the last 2 or 3 minutes to see finished product and operation, up to that point it's just putting screws in, lol.
