"You will be mesmerized... my precious... "


I have numerous optics, red dot, green dot, prism scope, but gold dot? I was skeptical at first, watched reviews on it. Each dot has its pros and cons. Dot sights are made for shooting fast and super quick acquisition. Made to look through....not at, imho. I leave mine on #8 brightness setting, for me it doesn't wash out in white background in bright sunlight. Its easy on the eyes and helps you see the dot if you are color blind to red or green. All my shooting buddies love it and also say the dot doesn't wash out it bright sunlight. Holosun and primaryarms are my go to optics!!!! Thanks!!! Awesome purchase!!!
