OP, I am also a left handed rifle shooter, but I never seriously considered a STAG after shooting one because where are you going to get spare parts? If my carbine goes down, I can just get parts from my other rifles if I had to in a pinch. LH upper, not so much. I've always trained on right handed models, so I don't mind it. Besides, if I was going to make a change, I believe an ambi lower would be more useful.
