Well to start off I would say a red dot scope will not work well unless you are shooting at the target form less then 75 yards. Red Dot scopes are meant for very short range like in urban combat situations that is less then 40 yards distance. I personally would go with an AMTc Professional 5x33L Illuminated Reticle Rifle Scope located here, http://www.opticsplanet.com/amprof5xilre.html
. This scope has low power of only 5x. It has a very nice illuminated reticle with windage and bullet drop compensation built in. You can dim or brighten the reticle and not many other scopes have this feature. It only costs $198.99 and this is a great value considering all you are getting out of it. I hope this helps y out. Thank you!
