Quality #1 - SightMark 3-9x42mm Triple Duty Tactical Rifle Scope

I bought this scope because my brother who is a retired Sergeant who was the Sergeant in charge of the Miami-Dade Department of Correction Training Range highly recommended it. I zeroed it at 100 yards at the CMP Marksmanship Park in Talladega mounted to an Ar-15, standard lower parts kit, 22" fluted stainless steel bull barrel, 11 degree target crown. Sent 90 rounds down range and by the time I was done I had 10 shot groups within a 2 inch diameter.
