This receiver is 100% complete and considered a firearm so we must ship it to an FFL holder.
This is just what the doctor ordered.
Like I said about my RPK receiver, these are very nice, sturdy receivers. During the trunnion holes I go through quite a few drill bits which is a good thing in my opinion. It means the steel is very well hardened and of good quality. I also love that they are a bit naughty and mark the 3rd pin axis point on the receiver. I've made several a case using these receivers and have never had a malfunction or a problem with fit.
