Hi Mike.
I had a gunsmith thread my Tracker I barrel for choke tubes a couple years ago. He used TruChoke brand chokes. They are made for thin wall barrels. It works very well. The whole job was $75 and that included 1 choke tube, X Full Turkey choke. I obtained another tube Improved Cylinder, from a member here at GBO. Now I can use my sighted Tracker I for turkey, as well as deer.
Please keep us informed on how your scope mount works out. Many folks here, I'm sure, will be interested. Good Luck with your project.
