Is it legal?

YES!

Are “80%” or “unfinished” receivers illegal?

We cannot accept returns on these 80% after ANY milling or drilling work has been performed OR after they have been installed into a milling jig for ANY reason. Please be sure you are up to the task of completing your lower receiver BEFORE you place your order.
