I was considering the Sport II or Ruger, when the guy behind the counter brought out the XM-15 MOE - 16 to compare with them - it was noticeably better made and higher quality compared to the other 2, for not a lot more money. I ended up purchasing the XM-15 MOE - 16 and never looked back. It's an exceptional AR-15, without spending over $1000.
Awesome gun and great customer service! The shipping was fast and free! Im very happy with this product. There were even a few bonuses not mentioned in the product description such as, a lockable hard case, M4 feed ramps, and a properly staked BCG. Now, if I can only find reasonably priced ammo!
