I'm a lefty shooter too... Basic reason I did the upgrade and I just think it looks better on my (soon to be) SBROn my shared AR's, I upgraded to Raptor handles for my wife, brother in law and mother in law, who are all leftys, plus ambidextrous safety selectors and B.A.D levers to encourage them to practice and shoot more without the akwardness they would have had in a right-handed world. It just makes it easier.
It's to their interests and my Benefit. We all get to play more.
