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?

No battery
Didn't come with a battery. Had to buy one myself. Otherwise a great red dot. Very easy to see even in the middle of the day.

Excellent Value option sight
This is a really nice option for those whom want decent quality at a bargain price. It holds zero really well. Very easy to obtain targets quickly. I am really happy with this.

So far so good. The red dot is very crisp & precise. I like how I don't have to worry about turning it on, just pick up the gun & it's on.

Awesome sight, hitting a 10" target at 100 yds. With a 7.5" pistol!
