Looking for recommendations. I bought a tactical solutions 6" .22 barrel for a browning buck mark as the original barrel had no threads and I'm wanting to put better sights on it than the original sights that'll "block out the little red schoolhouse at 50 yards". Question is......scope or some red-dot or? Not wanting to break the bank but also want something that I don't have to constantly screw with to keep zero. The new barrel does have a rail.
