I think I've seen this somewhere but I can't seem to find one. It's a holster that goes on the back of your right shoulder. When I saw it (possibly in my dreams) it worked amazingly. The sniper was lying down and somebody ran across from his left within his MED. he calmly (without letting go of his rifle) put his left hand over his shoulder pulled it out, shot the guy an was back in the holster and sniping again within a few seconds. It didn't flap about, wasn't in the way when prone and looked easily accessible. So do they sell these or have I dreamed up a great invention and made a scenario in my head that shows it works lol.
