I own with the M4a1 Silenced in sujo.

People have no idea where I could be coming from since there are so many hiding spots I could be at. Im also good at sniping with it at any level. Especially Foxhunt. One time I rushed the mountain and there were no snipers.(Trust me thats one of the luckiest things that can happen) I saw a terrorist at the river and I got a clean headshot on him. Then his partner started nading where he died and I saw where his grenades were coming from, so I hid in the grass and sniped him too. Hiding in grass with this gun is great. Especially in Enowapi. I hid in the grass next to the back breach and as soon as it blew up, a terrorist ran out and I lit his a$$ up. He didn't know what hit him. The silencer seems to add range and accuracy to the M4A1 too. When Im using it, there dosent seem to be a power diffrence. Maybe im just lucky.
Heres the maps I would perfer using the M4A1 silenced at:
1.Sujo
2.Enowapi
3.The Ruins
4.Night Stalker(Don't rush, take your time)
5.Foxhunt
6.Deathtrap(Good outside but stay in darkness inside)
7.Blizzard(Use trees and keep your distance)
8.Any other map with good hiding spots I forgot.
