for the Barrett, i go straight up CoD4 on it and throw on the ACOG
same with the Intervention

but i hate how unpowerful they make the Barrett on MW2

i have to put Bling on it, and put the ACOG and that other thing that boosts its Damage a little bit
AND Stopping Power, just to make it stabilized

but once thats done, it's like holding God himself in your hands

shotgun or thermal scope
