I am in the process of my first AR build. I am waiting on parts so I will have to limit my opinions to the quality of the machine work and finish. So far, I like my Mega. Very clean machining, beautiful even BLACK finish, I'm happy. In comparison, while looking at many new factory AR's at a recent gunshow, few lowers were as impressive as the Mega. As an example, I am surprised how many manufacturers hardly touch the forge separation lines, even the big names. Yet, there is no roughness or separation lines to be seen anywhere on the Mega. I came away with a new appreciation of what some of the smaller machine shops can turn out.
