Depending on the type of scope and if you do get a scope I would suggest to maybe get a hammer spur. I had to get one even with a 50 mm obj. lens. There isn’t much clearance between the scope and the hammer in my opinion.

Also check out www.virginvalleyguns.com for barrels if you can’t find what you want with in caliber's from Thompson Arms. Virgin Valley has a guarantee on the accuracy of there barrels. You can also get a hammer spur from them. Good luck with your new rifle and have fun.
