There is nothing "lefty" about the lower on a left-handed AR. The only differences are the upper, bolt, BCG and barrel extension. I personally don't see the point of a left-handed AR, and I'm left handed. The things that actually NEED to be changed to better accommodate a left-handed shooter aren't and the changes that are made are to no real effect. The upper needs to have the charging handle reversed and the lower should have the bolt catch and mag release reversed. This would, of course require different mags. Without those changes, particularly the charging handle, a "lefty" AR is a gimmick that you pay a premium for. No, thanks.
