I am a long time bolt action hunter with few semi-automatic sporting rifles. I am now thinking of purchasing a AR 15 most likely in .223 but am open to more moderized calibers. I do have a mini-14/30. Within reason money is not the problem. I do not think I would want to pay more than $1600. Can you folks recommend an AR 15 that I could purchase for use as a non-competition target or varmint model. I could go with a semi-heavy barrel but would like to enjoy using a slighlty heavier sporting barrel so I could carry this one in the field. I would think about a 22" barrel. Any suggestions?
