Spend your money elsewhere - Shield Sights Switchable Interface Red Dot Sight

I had this on my KSG12, only shooting slugs for a couple hundred rounds. It held zero throughout the multiple sessions, had easy adjustments and the reticle selection is nice. Especially for shotguns. The multiple risers you can choose from also adds versatility and comfort.

HOWEVER, when I went to the range after a few months the zero was off. Way off...like not hitting paper at 25 yds off. The gun wasn't resting on its optic, and the gun wasn't thrown around. I cannot trust this optic that loses zero just from being stored away.
