I have an EoTech 552 on my KSG. Works great.
Are you guys serious about it being heavy? If the weight of a red dot pushes the weight of your shotgun over the top for you I suggest you visit the gym once in a while.
As far as I'm concerned a little extra weight on a rifle or shotgun is welcomed as it reduces recoil and makes it more comfortable to shoot.
Not when the weight wants to roll the gun to the side.
