My buddy was shooting the scar after I shot a couple magazines. I was standing behind him at like 45 degree angle. Fuuuuuuck that was loud. Concussive force too. I had to be directly behind him to not have it that loud. I didn't notice that at all wile shooting it. Also the barrel got ridiculously hot after two magazines. Can was so hot after one magazine that I could see the heat waves through the scope.
