    Not the best, not the worst.

    This jig is strong and well made, but the instructions given are online, vague and dangerous. I have ruined two aluminum lowers trying to use this product in the manner Juggernaut Tactical proscribed online and had to buy replacement parts as a result. I'd use a router instead of the drill method they advocate online. Also, I would recommend buying a jig with the proper steel bearings to prevent egged out FCG holes. Since it's better than the home brew jigs on Gunbroker, but still not as good as many of its competitors, I'm giving this product a "C" grade. However, I am giving Supplying Patriots an "A" grade for customer service and communication.
