I'm considering purchasing a new ar-15 and left handed.The only manufacture I know of is Stag.The dealer spoken with highly recommends them.The model looking at is the 2L.In the past have only shot right hand guns w/o any problem,but I was told once you go left you will never go back.Aso looking at colt,armalite,daniel defence which are quality models.Advice would be greatly appreciated.
