Machining an AR15 lower receiver
#43
Ron, what he has there is known as an "80%" receiver, which means that the factory has already completed 80% of the machining needed to be done in-house. The only portion left needing machine work is in the center of the forging. As long as the total work done is <=80% they can sell these forgings as paperweights since they cannot "readily" be converted into a completed receiver. A 81% completed forging would be considered a "firearm" and subject to all the rules, regulations, and paperwork required the same as if you were buying a factory rifle off the rack.

There are places that sell special jig set-ups to those interested in completing that last 20% of the work on their own if they are so inclined to do.

They are geared more toward folks that may have a small home shop but don't own an industrial sized mill. A lot of guys who are still a bit nervous about using their new mill-drill will buy these jigs to help guide them, and are very successful.

Somebody told this poor guy those jigs were nothing but a waste of money, and he could do the work by hand just as easily. I'm guessing his name wasn't Bob. Sadno
