The Tru Glo Red Dot is a rebranded Holosun 503G. IMHO it is the best Aimpoint T-1 clone available because of it's price point which is currently $116 on Amazon.

It is also a 2 MOA Red Dot which I prefer to the larger 3 or 4 MOA dots found on many other popular models. It's all personal preference but I don't want to give up longer range accuracy since with the 2 MOA dot I can dial down the brightness and be good to go where the dot doesn't cover so much of the target at longer distances, therefore allowing for smaller groups at say 100-200 yards.
