Well, that is a pretty drilling isn't it.Sometimes a red dot sight makes the most sense, regardless of how it looks. I have a Savage 24F Predator, a utilitarian 30-30 Winchester over 12 gauge break open action firearm. The purpose of it is for feral hog hunting. A Bushnell red dot sight for the rifle in low light conditions - good choice. Does the shotgun barrel pattern where the red dot sight is - mostly, not perfect but good enough for 50 yard range.
That is an absolute sacrilege. A good flogging is in order.
Failing eyesight and the desire to continue to shoot your beautiful drilling would make you put just about any sort of sights on it.
That's a nice Drilling. I wouldn't put a red dot sight on it, but that's just me.
