Very Crisp Dot With Magnifier
by Randy -
I have a slight astigmatism and this is one of two red dots where I can get a nice crisp dot with a magnifier (the other being the Holosun 515 GM at twice the price). This looks and feels quality with both a low mount and a co-witness mount, including a riser for lower 1/3 co-witnesses. The window size is a tad bit larger than the MD 20. Primary Arms hit a home run with this!
