Requesting Help with a Personal Project

Currently, I am enrolled in a gunsmithing school, and for my final project I was very interested in attempting to turn an old, gross model 94 into a real-life version of the "Repeater HPR" guns for this game, and was wondering if there could be any way to veiw some more detailed in-game models or animations so I could get the specs down better? sorry if this isn't the place for something like this, this is the closest thing I could find to a contect someone.
