I am left handed. I use a normal AR. I personally wouldn't waste my money on a left only model. I suggest you try out a normal AR15 first before purchasing a lefty model if you haven't done so already. Shell ejection is not a issue. Looking for a model with ambi controls will be the only real need if any. I haven't even bothered doing that either.
As a fellow southpaw, I fully endorse this comment.
