John in AR did you not get your deer UNDER 100 meters? Hmmm? I have said before in a temperate climate in urban combat or jungle warfare or gun games the AR does have its advantages. Its damn good against hostile, assaulting gophers and aggressive bowling pins also!
100 Meters for an AR-15? I disagree with that totally. An AVERAGE shooter should be knocking down 3/4 silhoutte targets out to three hundred Meters 8 times out of 10. On a standing, man size target, they should be scoring 6 to 7 times out of 10. This is with a full size 20" AR-15. Even with a 16" carbine I would not say your safe at 300 Meters.
Terry, check the gun, its a 14.5" Armalite M15A2 (LE). In the past I have shot Service rifle with an Olympic AR15 with a 20" barrel out to 500 yds on a non windy day rather successfully. I have a 6 MOA Bushnell 1x23mm Red Dot scope currently mounted on the 14.5" rifle. Last year I shot a match where I had to engage 10 bowling pins at 200 meters. I got smoked easily with that 14.5" rifle, but I had a lot of fun anyways.
Melvin, this picture was taken at match on 9 April 2017, exactly 100 years to the day after a Canadian soldier went "Over the Top" with it on 09 April 1917, at Vimy Ridge on the Western front. During the match it functioned flawlessly much like it probably did 100 years before. Only problem was with the tiny sights they used back then. So is this "obsolete"? It works.
