I have had two ARs and loved them. This past Oct. I switched to the Sig 556 Classic. I am very glad to have made the switch and the Sig is a great weapon. The piston system is easier to clean and maintain. My Sig also has an emergency sight system if your electronic sight systems fails. All in all I love the Sig and I am very happy with it. Again, less parts and easier to maintain. The adjustable folding stock is great. I am glad I made the switch and I am really enjoying the Sig.
