I use a Pollington Red Dot Scope. It is so awsume it should be illegal. It eliminates the kisser and /or the peep. You shoot with both eyes open and is great for those who wear glasses. I don't however, the neat thing is with both eyes open optical illusion kicks in. It's as if you are projecting a laser directly on the deer. The Pollington was very expensive though. I did see another red dot scope in Basspro or Cabelas. It was under $100 and came with crosshairs. I would have gotten it if I'd seen it first.
