When it comes to a red dot for your AR15 there are a lot of choices out there. If you just want to play on the range occasionally and don’t want to spend much money just about any of the cheaper ones will probably right provided they are at the correct height from the top of the flattop (1.5″ centerline). But if you want to be able to count on it for competition, defense or military or LE use then the most common ones are Eotech or Aimpoint. There is also the fantastic Trijicon SRS which I am going to include as well. Please cast your vote and put some feedback below to have a good discussion on it.
