Yes you can! In multiplayer there is a perk called bling that lets have two attachments.
Hope this helps,
Commander.
You have to get all of the attachments on the ACR to get the mastery.
You get kills with the gun you want to unlock attachments for. If you see your challenges it will tell you what to do to unlock the attachment.
I don't see why not.
You select the weapon, then select the maximum attachments allowed, and then it takes you to the camouflage.
Red dot, grenade Launcher, FMJ, or an ACOG sight.
No, you must have the attachment already unlocked

You can to a degree. You can have whatever camouflage pattern you want, and change attachments. Other than that, that is all.
As far as I know, yes. You can. There technically the same as normal guns. In a certain way.
