Just purchased a DPMS Lightweight hunter AR in .308 and need to put a scope on it. Use of the rifle will be anything from target to Texas size hogs. Trying to find a scope that will do it all and inexpensive at the same time. I know, I will wake up from my dream sometime. Never had or used a scope. (aimpoints on our M4s if that counts) Millet? Suggestions? Thanks for your time.
