Sig Romeo5 on shotgun

[needmorecowbell]

I own 4 Romeo5’s. 3 are on ARs and 1 on a bullpup shotgun. The one on the shotgun started going haywire at the range today. Dot would get brighter than the sun then flash then fade out and then disappear for good. Changed battery and still same thing. Doesn’t matter if bright or dark outside. I’m wondering are these maybe not rated for shotguns? Anyone else had this problem?

Recoil would be my suspicion. I'd give sig a call or send em an email. In my experience, they stand behind their products.

I have one on my Mossberg 930 JM Pro Series tactical shotgun, never had an issue with it.
