I am looking to build or buy an AR 15 in .308 caliber. The purpose of the rifle is deer, hogs and target out to 500+. I reload for my .308 bolt guns and pistols and will most likely reload for the AR. I do have somewhat of a budget, mainly because I want to put as much into the scope as I am into the rifle. I don't plan on putting more than 200 rounds a year on it. For those that have built or bought AR 15's for long range target or field use, what do you recommend? Also in the future, I would like to go through the process of putting a silencer on it. I know it is a pain and $$'s, but sure would help me put a dent into our hog population. Thanks for any feedback.
