Re: lefty ar-15
I shoot an AR-15, and I am left handed, there is no problem with brass hitting me since the rifle has the brass deflector. As far as I can tell, the DPMS Lefty version only has the ejection port on the left side - the controls are still for use with the right hand. A ambidextrous safety is a must, and there are ambi mag releases available. Just adding the ambi safety is enough, unless you have the need to do ultra fast reloads like in a 3-gun competition (I still manage to reload quickly during 3-gun competition with the regular mag release).
As far as quality, I have heard that they are ok.
I keep nature balanced - I hunt everything!
