I’ve seen those; despite the claims, most of the time people get the buffer tube area wrong and ruin the piece. To each their own, though.

Why would you want an AR in 7.62x39 anyway???

The AR is modular and 7.62x39 is the cheapest ammo that Cabela's carries.

Nice thing about the AR is you can plug 5.56mm or 6.8mm in.

I agree that getting the buffer tube area right could be tricky.

I'm currently in the process of setting up a CNC mill similar to this one.


(Just barely big enough to cut the buffer tube area...)

As long as you get your workpiece zeroed out properly and you tell the computer to mill the hole and threads in the right place, it should come out right.
