Jig

FANCY!  I like.  Look how precise and well built that jig is.  (A jig for hogging out the waste in a 80% AR lower and make it a bit more than 80%.)

Having trouble justifying it for myself.  I'd never make enough 80% lowers into guns to make the jig really cost effective.  I know no one I could sell it to, used, when I was done, either.  Hmmm.

But spending too much money on gunsmithy things is not something I've been hesitant about before.
