Hello Gentleman. I purchased the 535 turkey/waterfowl combo last week. It shoots consistently high. I have the rear sight adjusted as far down as possible but still shoots high. About 10 inches at 40 yards. I will change the sights but would like some opinions. If I go fiber optic, I have read good things about TruGlo pro magnum series. But I am intrigued by red dot. I like both the TruGlotru-brite and Bushnell trs25. Would I be able to use these with the waterfowl barrel for ducks and doves? Or would I be better off with fiber optic? Thanks
