Ah that could be the issue right there, some engines are strict on texture sizes. Generally the "safe" sizes always double:
8, 16, 32, 64, 128, 256, 512 ect
Try just resizing to 512x512 and see if that fixes it. Another thing to check - ensure the entire arm texture is actually on the texture in uv mapping. I've made a few mistakes where the uv mapping went outside the texture - appeared fine on the model but once ingame - it DESTROYED the look.
Since it's one texture and the gun appears fine. It appears to be a UV mapping issue on the arms. However try the 512x512 first as it could be just that simple issue.
