I recently bought back one of my old markers, but it's been through at least four owners since I sold it last year. I bought it broken as a project gun, and it appears that somewhere along the line someone messed up the Sidewinder. The adjuster screw sticks out about a centimeter from the bottom of the reg, trying to screw it in further results in it going about a half-thread in and then skipping back to where it was (I think something might be stripped). If I air it up it doesn't leak or anything, but it can't be adjusted because of the screw. What are my options? Does anyone know the thread of the adjuster screw? Can I get a replacement for whatever the adjuster screw threads into?
