Ben, the link is dead but I think I have an idea of what you're talking about.
I just think it's hilarious looking at some of the tactical setups on Shotgun world. Guys with $500+ optics on a $350 scatter gun.
Right now I'm trying to decide if I like the look of the M4 style stocks on a shotgun. I like them mainly for ease in adjustment for different shooters. It's either the Knoxx Spec-Ops stock or the Hogue 12" LOP stock. I feel like the stock stock is too long for defensive shooting.
