I am starting a 6.5 Creedmoor precision rifle build on an ar-10/lr-308 system. I am looking for recommendations on a barrel, gas block, and muzzle brake (I know a suppressor would be best, but not in the budget right now). I saw a Wilson Combat supersniper barrel for sale on Brownells but I do not have any experience with Wilson Combat outside of their 1911's. I am looking to use the rifle for some minor long-range competitions and local long-rang matches, the distances can reach out to 1200 yards.
