AR10 Jig $80.00 http://billetgunparts.com/ar10-308-lower-reciever-jig/ That's the same place I got my AR15 jig that I have built 10 guns with.
AR10 lower $80.00 https://www.uniquefirearmsolutions.c..._black_308.htm These are some nice lowers with unique styling, although I did have to modify my jig with a Dremel and file so they would fit.
Daytona Tactical https://daytonatactical.com/collecti...fle-build-kits makes some pretty nice kits for a one stop shop.
The reason I have been putting it off is that all the AR10 80% lowers are DPMS 1st gen and I would rather have a GII style.
The GII uses mostly AR15 lower parts so field repair would be more universal rather than propietary with 1st gen.
