These are looking fantastic man, the texture quality is superb and the model looks flawless! Giving this out for free is definitely very generous of you. As for that second texture, it looks great! Although I wonder what it might look like, if the grip didn't so much have the camouflage as the rest of the gun, perhaps just a single beige/brown color that goes with the weapon? Just an idea
Keep it up man, I'd love to see what other kinds of weapons you can produce!
Cheers
Life would be much easier if I had the source code.
