Customer Reviews

I would buy again Review by Pops
This seems to a great optic to pair up with my MPX PCC. I have not mounted it and zeroed it at the range, so time will tell how well it works and holds up. However the the radical is crisp and clear, eye relief is good, and it appears to be well made. I have no reason to believe it will not perform well. (Posted on 11/26/2019)
