My buddy has one and I can shoot very well with it but just can't warm up to the way it feels in my hand.
I agree that it's built like a tank, heavy, very reliable and can handle +P and I think +P+. Great used prices of $300 and under.
But it ain't a Hi Power as far as looks and handling.
The biggest issue with assembling an AR isn't so much getting the parts together right - it's getting the right parts together. You'll remember the quality of a gun long after you forget how much you paid for it.
