A lot of time was spent finding a good gun model that would fit for that pose. Her usual F2000 is a bullpup rifle. so looked awkward in that pose, and carbines don't fit well in that pose, which I assume was mocapped from a full-length rifle. Eventually I found the T86, which fits like a glove.

This is based on that promotional shot of Old Snake from Metal Gear Solid 4 with his M4.
