Yes Colin is incredible . <| sep |> Well that or look for holes in things like your screens on cracks around entryways . <| sep |> What ' s the degree in ? Gender studies ? <| sep |> Well many people also use the Holo and red dot as well because they allow you to have more peripheral vision and are much better for close quarter engagements but of course you lose the advantage in medium to long range firefights . If you ' re good at keeping your distance and keeping engagements at medium to long range then use ACOG , if you ' re a more aggressive player who likes to rush and prefire corners and such then I ' d run HoloRDTriangle sights . Personally I run ACOG on everything because I have awful vision so I need that extra zoom sometimes .
