I have searched the sponsers of the forum but have not been able what I need. I am looking for a 77/22 barrel with a fast 1:8 or 1:9 twist to spin 60 grain subsonics. I also need the barrel treaded so that a silencer can be installed. does anyone know of a company who already manufatures this. the cost of a custom production may push this little toy beyond my willingness to justify.
