I am a first time AR15 buyer. Want to know people's opinions on a Windham Weaponry MPC vs Ruger AR 556. Both get pretty good reviews at different places on the internet. Windham is a little more expensive and I'm willing to pay for it if it's a better gun. Anyone shot either of these...

I've seen on here that some people have their 522/556 in OD green. I contacted SIG about it and they told me that they had not manufactured them in OD green for about 4 years. I would really like to get my hands on a hand guard, grip, and stock in OD. Also, if anyone has been able to duracoat...

Hi All- I have a SIG 556 classic (non-SWAT) and am interested in getting a vertical fore grip for it. Can I use the holes on the underside of the heat shield or do I need to buy rails for it? I'm trying to do this economically, but I want a sturdy result. Thanks for your input and expertise!
