Bulldog on Mrod hammer spring

[Tonycalves]

Bulldog with JSAR valve and what ever they opened up the TP to, with a Pitbull depinger and megamoderator. JSAR sent it back making 240+fpe which is awesome! And off 2500psi fill. Needed to retard that for home use.

Love how easy it is to change the hammer spring! I only changed the hammer spring to a stock mrod spring and a 1/4" spacer(give or take) and still got 900+fps. Started to cut the spring till it was topping at 820fpsExacts. On a 1700psi fill it waas 790-820-790  for only 5-6 shots. All i'll ever need for now. A simple spring swap and 240+ again. This really brings up the versatility of the gun.
