Just print screen what you need, paste into paint, luckily all gun info is nicely contained in square shapes, so just cut out the bit you need using the rectangle select tool. Copy and paste that into a new paint document, save as whatever image file you want, then job's done!
That's the rifle I was thinking of, but I want to know which specific variant it is. Got a ton of them. Just got the Sportshort, just need to wait for my leader to get back to base, he's the only one who can use it.
