Optics are terriable, - VISM Flipdot Reflex Optic 1x22mm 3 MOA Red Dot Sight

I realize this red dot is a cheap one but I am putting on a laser pistol with no slide action to effect it. The first time I looked through the dot I thought the glass was broke, red dot looked like a spider web, then I thought maybe it was my eyes, I brought it to a laser shoot and had others look through it and they all saw the same spider web effect and it got worse if you twist gun side to side. I will say that the plate provided did fit the Lone Wolf Glock 17 gen 4 after market slide.
