With stock valve stem, stock weight valve spring, and stock weight hammer spring. Valve has no porting or polishing. The breech is Cothran Machine with hollow bolt. Gun has a 12 inch barrel. Velocity Adjuster was unscrewed all the way, so no extra tension on the spring. Also used one of Anthony's Protops to test the gun with 12 gram cartridges.
