Call of Duty 4 Modern Warfare
This pack contains 3 skins.
Here's a new take on the M14 - straight black and evil looking. This rifle has had it's colors adjusted to look darker, and consequently more like a SOCOM M14.
This one changes your CoD4 M14 to give it a wooden body, appropriate markings, and added dirt and grime for a war-torn look.
Here's a very cool conversion skin by Ze limper that gives you the SP-only woodland camo M14 in Call of Duty 4 multi-player.
