then dont put it on, use it like a m4a4
plus its barely audible, footsteps already masks the silencer animation sound

M4A1 without the silencer is more louder than an M4A4. Plus if you know how to aim and have trigger control, you're good to go with a M4A1-S

I found a video a while ago about this

the a1s is objectively superior tbh. Since you're talking about CT side 90 percent of the time you wont be taking on more than 2 in any given skirmish. So in my opinion the extra 10 bullets is not nearly as important as the ease of hitting headshots with the a1s. If you put an a1s into someone with a good spread control's hands, that thing is like a fucking laser pointer.

doesn't really matter though because ur gonna drop the m1 for an ak at every opportunity anyways.

I agree about the swapping for Ak every chance anyway lol

I personally use the M4A4, but depending on your rank and skill its different.
The main difference between the A4 and the A1-S is the ammo capacity, and the accuracy.
The M4 has 30 ammo in one clip and 90 extra. It makes a lot more noise and its better for higher ranked players because of spraying. Its a little bit less accurate than the A1-S. If you are playing rifler or entry fragger you are better off with the M4.
The A1-S has 20 ammo in one clip and 40 extra. Makes a lot less noise and you will not be seen on the radar as much. It's more accurate than the M4. If you are playing rotator or stalker(lurker) the A1-S should be better. 
In other words for lower ranks use the A1-S.

M4A1-S is more accurate however the M4A4 is more powerful

^false

both have the same damage rate.

[SmG Prodigy]

^I second that. They're both 4 or 5 shot kill depending on where the bullets hit. Both also need to two head shots to kill an enemy if they have a helmet.

What do you guys think the pros and cons are for each, I need advice on which to use.

depends if you want to spray you enemies  (m4a4) or one-shot him (m4a1-s)
