My tophat came from the factory set @ .116 to the top of valve stem(or whatever the brass piece screws into is called with the 2 holes) & the brass piece is recessed .020 below that for a total of .136. It seems as if they raised the tophat to lessen the gap between it & the breech when cocked. Can I raise the brass piece so it’s level?
Talon tank. it’s the piece the tophat goes through or screws into. I meant the brass piece has 2 holes or dimples for a tool to screw it in or out.
