A friend of mine is looking for someone that builds quality 6.5 creedmoor uppers or rifles with a 22" barrel for a decent price. He wants to spend around $1600 for the entire rifle and about the same or a little more on the scope. He has Leupold Mark iv illuminated scope and really likes it but was thinking about going with a nightforce for this build. Is there a better option scope in that price range? I'm getting tooled up to build ar 15 uppers and might get the tools to do 10's if need be.
