Get what you pay for - Vism Micro Red and Blue 1x 25mm Reflex Dot Sight, 3 MOA Dot Size

I bought this just to try it out. It’s a pretty crappy optic. Dot is blurry no matter how bright or dim and I don’t have faith the seals will hold up on the glass very long or take much abuse. I would recommend just going with a namebrand optic, it’s twice the price but all of the hundred dollar ones I have are vastly superior to this one
