I have a Mossberg 930 Tactical with a 1913 Rail. I’m looking for a red dot that will handle the recoil from a 12 gauge. Will this sight hold up to that?
Dustin C on May 12, 2018
BEST ANSWER: This would be a good question to ask at the Holosun website.
Does this have solar?
Eddie on Mar 21, 2019
BEST ANSWER: No, other models do but this model doesn’t. I’ve had mine over a year and still haven’t needed to change the battery with weekly use mostly and sometimes daily
Can flip up sights be used with this sight?
Ken G on Jun 18, 2018
BEST ANSWER: The 1/3 mount will cause it to be right above the sights..buis will be seen on the lower 1/3 of optic view..if you want a perfect cowitness you need an absolute.

What type or height mount should be used with this when equipping it to a tavor?
Lek15 on Nov 21, 2018

I don't think you can beat this deal when these things are on sale.
I have an astigmatism, so no matter what I will only be able to see a little star (never knew about it until I started using red dots). That being said, the adjustable brightness is great to shrink the star. The shake awake works great. Glass is clear. Why are there no add on flip caps for budget red dots???
