This weekend I got to put some rounds down range, got a chance to test out a new prospect carry load for my XD (Federal HST), and also got a chance to test out the China-Com replica 3X Magnifier on my AR. Yes I know I should of bought the real-deal, but $600 for a damn monocular, no thanks. Mount had no issue, clear, crisp, image, helped tremendously trying to re-zero the EOTech at 100 yards, and with a 62 grain opposed to 55 grain round. My only compliant is that the eye-relief sucks, and I might get a swing to side mount opposed to the twist off that I am using now.
Finally, a tip for any red-dot/HWS user, if your zeroing in your optic, use the lowest brightness setting.
