Crosman Collets Pair to unscrew Valve body
Crosman Valve Body Collets to unscrew the valve body without marking. This is for two collets to grip the Valve Body so you can get the exhaust valve and spring out of the valve body for tuning or servicing. Photo shows one of the modifications you can do to the valve body when you have undone it with the collets (not shown).
Always check the power to make sure the gun does not exceed your limit, after changing any parts.
