80 Percent .308 Lower Jig
BUILD A FIREARM
80% .308 Lower Receiver jig is the highest quality lower receiver jig on the market. Every piece is replaceable on the jig. There are three top plates that are interchangeable to allow you to mill the fire control group. The side plates are fit with a drill bushing to allow you to properly drill the trigger and hammer pin.
I own 80% lowers in about every feasible alloy or polymer available. A jig is not essential, but without a LOT of money invested in expensive tooling it's foolish to even contemplate trying to finish a lower that will be functional, much less safe. I have about as many jigs as I have different types of lowers. I have mills and presses, bits and taps, dies and end mills, etc. But without a tested and known good CNC and a redundantly checked G-code for your lower, it's best to use a jig.
This is singularly the finest example and execution of a jig I've seen yet, period.
I'll restate for clarity, my hands have not touched anything superior. At best, and a much greater expense, half the quality. If you're going to do an Ares 80% .308, buy it. If you do not already have all the endmills and bits, I strongly suggest purchasing those too.

Awesome product! High precision, well built, Excellent instructions!
Hole spacers are amazingly strong! Easy to use!
I used a Grizzly mill with DRO. Drilled out the bulk and then milled to finish. Took my time and it came out beautifully! I am a software developer and this is only the 2nd time I have used my mill. 'Nuff Said! Excellent Customer Service and Tech Support! I'm trying to come up with an excuse to build another!
