Yeah, the camo pattern to me screams "tacticool" and that doesn't fit his character at all. However, if it were an option and I could customize the gun whichever way I wanted, I wouldn't really care. As it is now, it fits with the jokey feel of the game.
I didn't even know what that was so I googled it and it looks like a terrible camo pattern gun from Counter Strike..something we've already got ingame so I agree with you. The whole point of weapon customization is to give us individual choice to make it look the way we want and personally I'd just go all black.
Regarding the M4, we already have that and it's all black. I'm confused by the 2 round burst and the way they made it sound though, sounds very unlike a rifle if that makes sense, atleast compared to the agency unlock assault rifle. Same goes for the Jaeger Lancer variant, reminds me of counter strike 1.6 sound effects. Very dated and gamey, not authentic at all..ahh I'm going off topic now lol
