f*ck suppressors I have them on 2 guns, and that's IF I want to be stealthy. So in other words I hardly ever use them. I made the mistake of buying all attachments on my guns in singleplayer and they sounded/looked like crap. I keep my guns bare and gold. .
Sorry to break it to you but the gold guns look like crap so you've done yourself no favors.
I made all my "hood" guns gold. That's the AK, sawed off and standard MG. Makes me feel like an Arabic dictator.
