80% Arms jig with New Frontier lower
« on: April 27, 2017, 07:52:43 PM »

I have the OG 80% Arms jig (non-universal). I just ordered a New Frontier 80% billett lower (anodized).
I know that the jig wont work as-is, and needs modification.
Should I go through the trouble of cutting the 80% Arms jig or hawk it and go get the Modulus Arms setup?

For cutting, does anyone have photos of how much material I need to remove?

This is a picture of the material I removed but it may have been more than I needed. I modified this jig for a few different lowers.

Any issues getting the lower centered after that cutting? And did you just dremel that all off?

I didn't notice any issues. I removed it but putting an end mill in the drill press and then using it as a mill and my gloved hands as an X-Y vise. I controlled the depth of cut by setting the height of the drill press table. Very low tech. I'm not sure it's worth the trouble if you can sell the jig for a decent price. Your call on that.

I have the ar15 ezjig and the modulus 308 jig.  I find I get the best results from the modulus jig , using the 3 flute ezjig mill bit.  I still plan to purchase a modulus ar15 jig when my budget allows.     
I have a couple other jigs that I find pretty useless.

The ezjig is a good jig, and i like the wider top.  I like the way the modulus sets up, and holds the lower.         

Depending what has been completed already, and what style of lower you have, one may work better than the other.

I also plan to get the little jig that eparmory sells just because..........
