Currently I have an SRO 5moa, DPP 6moa both red dots and a Holosun 507c with 2moa dot and 32 moa reticle in green. All are slide mounted on pistols. I had a DPP with the triangle and traded my buddy for the SRO. I am 70 years old and need a bright dot. The reason I traded the first DPP was the dot was not bright enough. When the DPP 6moa came out I figured Leupold had corrected that shortcoming. Wrong on my part.
Now, if you are 30 years old you are probably wondering what the heck is this old man talking about. Those dots are plenty bright for me. If you shoot long enough you will understand. Old eyes need more light and in the case of red dots, more brightness. I just bought a 10/22 for rimfire rifle open. The SRO is my brightest red dot, but I still need more brightness to acquire the dot quicker. Are there any red dots with a brighter dot than an SRO? Thanks for the help.
