I have this Airmaster 77 that was given to me in pieces and the valve was damaged by who ever took it apart, looks like it was done with a pipe wrench. Back half in pretty bad shape. A 13xx back half barrel is the same length. Brass nose peace of 13xx fits perfect. Same size as old 77 valve. Port needs to be drilled a little deeper but that's about it. Internal othe peaces are same except plunger needs to be shortened. I need feed back what do you think. Any Internal mod also would be great. Iron Hand
