I found 3 different shotgun scopes on Amazon.com and I can't decide which one I want. I don't remember the model names but I do remember brand names. They were : Simmons Bushnell konus All three scopes have at least 4" of eye relief. I know single shots beat the crap out of cheap scopes. Will the limbsaver barrel ring help? The gun I plan to put it on is the h&r ultra slug 12 gauge with the thumbhole stock that I'm saving up for.
