Add the cost of a rear sight and a magazine
Don't forget your tranfer fee
But yep....that is cheap but I'm well stoked
Note this. It's probably cheaper/better to just have your FFL get you a lower. By the time you pay $20-$30 for a transfer on the Anderson lower, you could have had the FFL get you an Aero precision or better for the same price. Or he can prob get you the Anderson for cheaper in the end.
