Well I went and got that TCR83 from my LGS it has a 22 hornet with open sights, 7mm-08 and 7mm Rem mag both with no sights. They all have scopes on them Burris's on the 7mm's and the hornet bbl has an old Weaver K-3 with the TV (Widefield) view. The gun and BBLs are mint. I too would like to add some Barrels, not sure whats out there yet but I like the odd ball calibers too. I probably will part with the 7mm mag BBL as I never was too fond of the caliber. Nothing wrong with it just a personal preference. They are quite an attractive gun to me and I do like the double set triggers.
