Ambidextrous Split Stock for Oculus and Vive

This is a remix of Djacobs123 split stock that makes it ambidextrous as well as adding shoulder stocks to each hand. I made it to play Snapshot VR, a paintball-inspired VR game. I am a divisional paintball player, so the ability to shoot with both hands is a required skill.
