80% Lower Deals / Decent price on 308 kits
« on: May 21, 2017, 09:47:09 PM »
Pricing on these looks very fair.

~$535 for the 80% lower, lower build kit, and assembled upper...

I have no affiliation with this company. I was shooting with someone yesterday that had one of the rifles (he used an Aero lower because he didnt have the machining tools)

Main 80% Lower Discussion / 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?

Main 80% Lower Discussion / New Frontier Lower

Anyone completed one of the 80% lowers from New Frontier? I really like the features they have, just wondering how the fit is in the jig.

Im putting a rifle together now with one of their stripped uppers (well, actually a JBO Spartan_ same thing) they're pretty nice.

I'm using the easy jig, and when drilling the hole for the safety selector, I've noticed that the aluminum will spin with the drill bit as it is spinning damaging the anodizing near the hole. I use small "passes" to minimize the size of the chips, but it seems that they always mar it a little. This is due to the gap between the jig wall and the lower.

Anyone have a method for eliminating that damage? I've considered putting an o ring or thin nylon washer between the jig and lower to minimize the space the chips can travel.
