The biggest issue with assembling an AR isn't so much getting the parts together right - it's getting the right parts together.

And they still can't do better than those ugly/cheap looking railed gas blocks.
I dont think it comes with that gas block , that pic looks like a computer production if you scroll thru the pics you will see the gas block they use its more of a troy type low profile . Really bums me out that all the machining and sanding marks were left in it for that kind of money it should have a mirror finish http://nemoarms.com/eye-candy/
