Good, inexpensive circle/dot sight option - Swampfox Liberator 1x22mm Red Dot Sight

This is a great holographic sight for the price. It has very decent glass clarit, and is much less expensive that other circle/dot options that I researched. It does have some ghosting or blurring of the reflected aiming image, and the image projector impinges slightly into the field of view on the left side of the scope window. But for the price point, I probably shouldn't have expected perfection.
