Losing the caps might be the first step. In case you didn't know...caps makes it look like YOU'RE SHOUTING.
I've seen some night vision scopes online, but probably the best option is to attach a regular scope that you choose onto a 40mm Pitcanny rail or Weaver rail then attach a night scope in front of it.
Or a Night-then red-dot scope.
With daytime, just remove the night scope. You can read about how nightvision scopes work on
www.howstuffworks.com and you'll note that night vision units are not designed for bright light and can be damaged.
