Be careful.


Well, the finish on the equipment is nothing to write home about which isn’t that big of a deal. However, what I am thoroughly upset about is that when I ordered my lower parts kit by Rise Armament while I was away on training in the military, they did not include the bolt catch roll pin. So I had to go to a local store and pick up a whole new set just for the one roll pin. Ridiculous.
