Hi i start my training soon. I'm left handed and left eye domminant. My left eye is perfect but my right eye is slightly inferior. It still good enough to pass the eye test tho, but I use my left eye for focussing and whatnot. I'm a bit worried how this will affect my shooting as i hear the sa80 can't be fired from the left shoulder. Is it possible to use other weapons such as the minimi, and gpmg left handed?
