Im currently looking for a AR type rifle. I have seen alot of AR rifles and just seen the Sig 556. I was wondering if any of you own a Sig 556 and can let me know what you think about it. Also compare the Sig to a AR. My budget is around $2,200 right now. I will be going to a gun show in 2 weeks and want to have some help on my decision. Thanks guys and gals.
