If I had the ability I would actually reduce the amount of porting for the cycling of the bolt, so that there would actually be less air used per shot to cycle the bolt. AND it would cycle smoother.
and it would be less consistant. less force pushing the same or greater bolt resistance would reduce consistancy(I say greater because a reduction in cycling force would need an increase in hpr pressure to balance out, and therefore an increase in bolt resistance.)
also, if you want to reduce the amount of porting just push epoxy into the existing holes that you want to fill, its really that simple.
