Inner barrel metal stock??
 

I'm looking for a supplier for some custom inner barrels i plan on making and require some 6.01/6.02/6.03 metal stock. Does anyone know ware to source it?

perhaps a piping manufacturer? You could give them your specifications and they could make you your products. that is really all i can think of atm. Here is a unique idea. in paintball they made Carbon Fiber barrels because the barrel wouldn't be affected by temperature changes. think of trying something like that out for airsoft.

Carbon fiber is cost prohibitive for the barrel, though I'm going to work on a carbon fiber stock for the L96. Shouldn't be too hard to split the current stock and make a mold for vacuum forming. ;)
