[redfish]

I so far have

14 barrel crosman barrel
millet ringed 4x barska
muzzle brake
trigger shoe, sear spring & guide, delrin shims and the pivot pins polished trigger sear
stainless/hex head

it hits what i aim at, but i am hoping for a bit more power

a lot of options, fluted hammer,valve. any one have any experience giving these guns a bit more kick
