does it have to be a scorpion? i have a .177 Ultra with a regulator, rowan trigger, tench pressure gauge, HW moderator and has a wooden stock with UK-neil adjustable cheek piece. Don't know much about it, i shot it over chronograph when we done deal and was shooting JSB exacts at 11.3 so my guess would be 11.6-11.7 with bis mags. I took it as part of a px deal and will sell it for what it owes me
