M4A4 or M4A1-S

I like the M4 more, since it has more damage and accuracy, I see it that way.

They both are pretty good in their ways. The first one is used to engage enemies at middle/long-range (because it's more precise) while the second one is a bit better to use at only middle range and it's silent unlike M4A4

M4A1-S better if you want go B.

M4A1 in my opinon. Is quaiet and beterr dmg

I play with the M4A1 because i am remember CSS

The A4 is simply better close range and the A1 is better at longer ranges. Both sound amazing, I usually choose to use the A4 tho because it's more fun to use in my opinion.

M4A4 is beter but is have most damage on long distance

Both guns are boss and don't mess with boss.

i prefer using the m4a1-s ... it's easy to handle and good at pre-firing smokes (No Bullet Trail)
