do people not realize that MW2 weapons still exist in game?

i only say this because i run the victus xmr built to deal MAJOR PAIN at long range , with the only way not to die is to run the survivor perk, and i can always hit my head shots thank to my scope
now note this scope is not cheating at long range it just gives a distingct advatage
here i am clicking heads , and i ecounter a anouther sniper , i line up the shot and get the servivor icon and buddy duck and hides , give it some time and i have head shot him from the same spot about 15 times now. and then he accuses me of hacking, very rude mind u . so i pop him again and he complains about me in SC (server chat). i do die later but thats bc i wasnt paying attention to my rear,
mind u if he wasnt using the survivor perk i would have need one bullet to win that long range fight.
in this case MW2 beats BO7 weaponry as i had the distinct advatage
just some fun in the end thou so happy hunting and remember MW2/3 guns are still potent in the right hands and senarios
