Back in the 80's this was possible but now a days i'm not so sure?. You could choose your action, tune, stock etc and the rifle would be done in about 4 weeks. Around 1989 I asked venom to rebuild an HW80 of mine to my spec...3 weeks later I had a HW80k with a full lazaglide action, Mach 1 trigger, Mach 1 barrel, full reblue and a factory MK1 walnut stock. These days something like this would take a little longer. Mach 1.5
