I’m getting ready to start my first AR9 80 percent lower. When cutting the above trigger slot it says 2in down off the jig plate. I 3d printed my plate and it measures .600 +/- .005. So I assume 1.4 inches is the pocket depth?

And the one next to it .630?

Thank you!

I’m having issues with several 80% Arms reveivers fitting in the Broken Arms Jig. The AR9 receivers don’t fit in the profile of the jig and the Space Liberator AR-15 holes don’t quite match the pins.

Has anyone else had issues? I thought pretty much all AR-9 receivers would work in the Broken Arms jig?
