A for effort! You do have alot of streaking everywhere thats not facing up, and somehow the grip is missing a side, that should be a quick fix, then go back and texture map all the verticle spaces :)

yeah, that missing polygon is a bother. your also missing the stock hinge assembly , stock ejection button, mag release lever and fire selector. the trigger and trigger guard are much too thick and the trapezoid hanging in the trigger guard is the safety switch which is only on the left side of the gun with the fire selector. it appears you’ve modeled the front site correctly but the charging handle needs a cut out to see the front sight when you look through the rear sight that you missed. one last thing, the ejection port is only on the right side.

Great model, cd184!
