Skewed reticle - Holosun Enclosed Pistol Sight w/Multiple Reticle System

Like others have said, the circle dot reticle for this sight (mine was green) was significantly distorted right out of the box. Placed dead center in the window, the reticle appeared "squashed" from the top down, and would then distort accordingly when moved even slightly up, left, or right of the window's center. The only time the reticle looked even remotely circular was when it was moved down the window towards the bottom.

I'd gotten this sight thinking it was probably an improvement over the older 509t; newer technology would trend towards a better result. Or so I thought. After returning this, I purchased a 509t, and the difference was night and day. No distortion at all. Slight tint to the glass in certain lights, but a minor gripe compared to the fact that the 509t's reticle was vastly better. Hopefully Holosun corrects this is later version, but as it stands now, I can't recommend this.
