After doing some testing with the SCAR, it seems the SD suppressed versions aren't very... well.. suppressed.
At first I noticed some issues when I was trying to replace them into a mission I had, swaping out the M4s with the SCAR-L SD. But all of a sudden, ever shot was triggering the opfor. When me and my clan mates spread out, there could hear my shots with it... The snapping sound, where as the M4 wasn't detectable
I then tried out my theory. I put in a wall between me and some enemies on a test map. I then shot a single round of the M4, and nothing, they acted like nothing changed. I swaped it out for the SCAR-L SD and the minute I shot it they droped down and looked at the wall I was behind.
has there been a fix for this that maybe I didn't download?
