What kind of rifle are you looking at? Bolt, single or semi auto? My co-worker has an ar15 and he says that it is one of the more accureate 223 semi autos. He also says that mini14 is not so accureate. I have yet to shoot my new 243 single, but I will have more opinion after this saturday morning. We will be shooting both the 223 and the 243. EJ
