Nice!
Looks like the top plate doesn't sit directly on the lower, so it won't get chewed up like the jig I've used in the past. Am I right about that?
Also, where are you getting your anodized lowers and will a Gen2 PMAG drop free from the magwell?
I look for ones that have the KEY HOLE Forge mark on them and yes all P-Mags fall out easy.
Bear creek arsenal has some now for 40.00

Anderson Arms sells 80% lowers too.
and many more sites with these
Does it work with a milling machine as well ?
The jig will not work with a milling machine as the router Plate has a Collar on it to keep the bit from gouging the top plate.
