Hey!
1.) What do you guys think about a sling attachment? It would increase weapon change speed very slightly. You could switch to and from frags faster as well with appropriate animations. It would simply be another amazing attachment in the game
2.) HIGH level camouflage paint for your weapon: This should only be done at very high level, to replicate a hard core SF unit. But having an option of painting a color scheme over your weapon would be amazing...
3.) Camo wrap for a specific marksman rifle: Be it an M24, Dragnov, RSAS, and SV-98.(God forbid, right?!)
