Red dot on shotguns?

[NinjaHunter]

Hey guys,

I've been doing some clay shooting lately, and I find it impossible for myself to hit a single clay with both eye open. Each time I shoot with both eyes open, I keep seeing two barrels. It also doesn't help that my mossberg 935 doesn't fit me, even with the shims. And that my mounting technique is not the best there is.

So, I kind of thought of buying something like this: https://www.easyhit.com/product-page...-av-px-r1000-1.

My main point is: I kind of just want your guys' opinions and experiences on shotguns mounted with red dots

FYI: the end goal on my shotgun shooting is being able to do running shots on deer.

Thanks for all the inputs.
