Editing Official Missions

[Cormega 0]

Is it possible? I'm having a hard time with that stupid M4QSD or whatever it's called, it's like a BB gun....yet, when I use the M240 or a couple of other guns, I can snipe with them? The M4SD I get lots of bad shots with it...any tips for using it better, or just editing the mission to have a different weapon???
