NOW this thread is picking up! I was thinking about going "Youngblood" and seeing if Mike had any 18+" barrels left. I like how the dropout is just an extension of the body tube, but I think in trying to capture a modern old-school gun a back bottle valve body with a reducer routed to a bottomline setup may be the way to go. I know the dropouts were quite old as well, but I think I'd rather run CA for practicality (I play scenario). The stick feed will happen, for sure.
Now I just need to figure out how I'm going to run the tank. I'm not a stock fan, but I DO love the aesthetics of a thermo tank snugged into a tank ring, so I may hunt a bottom-mounted tank ring, sans stock.
