I have noticed that the text on the texture of the MX rifle family says "6.5 x 38 mm", but the actual caliber that rifle uses is 6.5 x 39 mm :) So, please, check that out and patch it. It's not a big deal, but my sharp eye spotted that tiny detail there.
Here is the link to a picture of the "issue"
