I am interested in a 'tube-type red dot' for hunting? The standard sights are just too blurry for my 60 year-old eyes. Don't want to go too cheap, can save for a while, if need be? I have looked at the Weigand 'mini' and barrel-clamp style mounts, are there better choices? I wouldn't give up on open sights, but need a better option for deer hunting. THANKS up front for your replies, hc18flyer
