Like this one:
Anyway. A friend of mine OCs (warm weather, CC in cold weather) with a shoulder rig now that he is predominately confined to a wheel chair. Unfortunately he is wrong-handed (left) and the cane he uses when not using his chair seriously impacts his ability to draw from his shoulder rig. He is practicing with using his right hand.
Also, now you have, or will have, the ability to carry more ammo since the added weight of several hundred rounds, in mags, will be born by the "wheel chair" and not you. Can you rig up some kind of swivel mount for your LGs?
