Some decent sniper gameplay there dude, well done. I find it hard to quickscope in public matches, but I can quickscope really well in private matches. So kudos to you
You're obviously not in OpTic though, but I guess you put that in the title to give people a hint of good quickscopes / sniper gameplay.
Otherwise, there's nothing much you could improve, except your secondary. A handgun is much better suited for a fast draw.
