Personally, I think buying a scope for a shotgun is kind of rediculous...which is exactly why I want one, lol. My shotgun (Mossberg 590A1) is just for home defense. And I want a cool scope to mount on its picatinny rail. This scope should be ideal for close range... Suggestions? I understand that a scope may not be ideal for home defense. I don't need any lessons from y'all. Just suggestions on cool scopes that are ideal for close range...thank you.
