So I have a H&R single shot 20 Ga that im going to get threaded for a turkey gun so im wanting to know what sights are out there I can put on it. One thing I really like using this for is my squirrel gun so I don't want to put a red dot on it so what type of sights can I upgrade to maybe some type of fiber optic something I can easily throw on target for when they are running tree tops and for use for turkey.
