I suggest looking at a gun, then understanding how it works before, trying to sell the model "of said gun", just a thought.
From my knowledge there was never a Karabiner 98 Kruz, made left handed, and anyone that has seen combat. Will see this model is needing a rebuild. no one that ever new about a gun would reach across the action, to extract a bolt, The model itself seems fine, but the animation should be scrapped, along with the texture.
My advise know a gun before you model it for sale. this may seem bad C+C but it's the truth.
If your not on the edge your taking up to much room!!!!!!!
