Its a great combo, IMO. I just bought one in .410 and love it. I have reflex sights in 2moa ,4moa, 8moa .I have used my 8moa the most on my 20ga. weatherby. What i like most about the 8moa is at 40 yds it covers the head just about perfectly, so i know im at 40 or close to it. This new holosun is 6 and liking it so far love the optics ready cut out. Mounts nice and low, and of course its a mossberg 500 which speaks for itself.
