it looks pretty awesome, but the anatomy of the rifle is a little wrong. For example the scope is too large for World war one type rifles, they weren't much more than a cross hair in a steel tube with a little bit of magnification. Another example is the scope's placement, it is directly over the action and would require to load the rounds by hand into the magazine. The bolt is on the wrong side of the rifle if it were to bring it up to right shoulder the bolt would point inward toward the center of it's chest, this is wrong because not only are you needing to move the supporting hand to use the bolt (forward/left hand) and then it would have the probability to eject the casing which is going to be hot into its face/clothes and generally not feel good. the last two problems are the length of the hand guard and cleaning rod ,the rod under the barrel that is stored in the hand guard, having a full length hand guard would allow for the rifle to be rested on something farther toward the end of the barrel and not actually be resting on the barrel (its bad to do so), and gives you a proper place to store the cleaning rod which needs to be just shorter than the barrel.
Wow, I wrote an entire review on the rifle and to be fair unless you're a gun nerd like me you really aren't going to care about whats wrong with the rifle or not. it is a very good looking piece of monochrome art. one suggestion I have is, if you want to show that the rifle has a bolt have the robot hold it like the robot is but in the robot's left hand and the bolt moving to the right.
