I just viewed a 2 hour program from Fort Benning GA entitled 2018 Sniper Ultimate Championships. I was disappointed that the host did not talk about the rifles, optics, night vision or suppressors used. It appeared that most rifles were AR10 and only a couple of Remington 700 bolt guns with heavy short barrels. I assume that all competitors had to use the NATO 7.62x51mm. I make that assumption based on two things. One, maximum target distance was only 900yds and as I recall there was only one or possibly two targets at the distance. Two, the low B.C. bullet for that caliber makes shots beyond 900yds very difficult. I am really interested in the AR10's that were used. Any info would be appreciated.
