Before I start don't flame me.......I am trying to build a gun as cheap as possible. Got a 243 AI on a Savage Action with 20 MOA rail I am putting a Tasco 6-24X42. It was $70 bucks which brings my total gun cost to 650 bucks. Go me. anyway how high do they need to be all my other guns have been high rings but i don't want to be arching my next to see through the scope. My cheapest of all my rifles and the most accurate of them all with my old scope.
