If I send you guys 3 Draco AK pistols along with 3 PWS FSC30 muzzle brakes, how much would you charge to put on a small adapter (to get each barrel to 16" with the PWS) and the perm attaching of those muzzle brakes? I'll also have 3 Ace stocks that need to be installed after the muzzle brakes. They require that two holes are drilled and tapped on each of the Dracos. How much would it be to get those installed? Thanks in advance.
