Iam a lefty and just found out about there left handed ar's. I really like this rifle, and would obviously use it for varmint hunting. How do they hold up, are they accurate? It says they are 1/2 MOA. It is kinda expensive for me. Is it worth the money? There isn't any way I could test one or even hold one beforeI buy. I would have to order it and give a down payment. Does anyone own one, they are kinda new?
