1, Too many sides on the barrel. 8, 6, or 5(sometimes 4) will suffice.
2. Certain areas don't match up with the rifle.
-Right before the barrel extends from the gun, there's an even larger cylinder that stems from it.
-The roostering handle is not at a 45 degree angle.
-The pad on the end of the stock is actually thinner than the stock.
3. Not too big of a fan on hands, but if I were you, I'd make the rifle proportionally small enough to where the hand holding the rifle is at least like a foot away from the body.
