But precisely finishing the last 20 percent of a lower receiver has still required access to a milling machine that typically costs tens of thousands of dollars.
Whatever. I made mine with a $350 micro milling machine from Harbor Freight. The template kit to mill & drill the other 20% of the incomplete lower receiver was about the same cost as the 80% complete lower receiver. So all of the parts & tooling in sum total less than $550. Plus I use the mill for other things and the template has resale value. Also FTA:
Defense Distributedâ(TM)s machine canâ(TM)t carve pieces as large as its competitors, but its small size makes it more rigid and precise, allowing it to cut an aluminum lower receiver from an 80 percent lower in around an hour. Thatâ(TM)s a task Wilson says would still be impossible with todayâ(TM)s cheapest hobbyist mills but doesnâ(TM)t require five-figure professional tools. âoeWeâ(TM)re making this easier by an order of magnitude,â he says.
I think that they meant to quote him as saying it is POSSIBLE. An order of magnitude is a gross overstatement, given that this was the 3d milling version of trace paper.
Subversive ambitions aside, Wilson doesnâ(TM)t hide the fact that the Ghost Gunner is also a money-making project.
