I have a Simmons Prodiamond 2X shotgun scope on my Mossy 835. I bought it used and have punished it myself for the last 6 seasons. I love having a scope and will always have one on my turkey gun. Last year I sat in the rain twice. I took some extra precaution to keep the scope dry---but even when it got wet---I could still see plenty well enough to aim at a turkey. I have had no problems with the scope and there are so many advantages to one.
