The Router Jig Extreme is our universal solution to finishing any 80 percent AR15, AR10 or AR9 lower receiver on the market. It doesn’t have to only complete our 80 lowers. We believe in the “buy once, cry once” mentality and that certainly applies here for this jig. For any accidentals or excessive wear on your 80 lower jig, not to worry, we have replacement parts on hand for you ready at a moment’s notice. 

What Is An 80 Lower Jig?

An 80 lower jig is a tool that’s been designed to help you accurately finish an 80 percent lower receiver with tight tolerances, making it compatible with most AR parts on the the market. It’s really just a fancy template that helps anyone build their own firearm. These jigs utilize handheld routers to quickly mill out the solid, “blank” portion of an 80 lower to finish it into a “100%” firearm. Consider the 80 lower jig like a portable fixture similar to something you might find in a CNC machine, except for your own home, and *much* cheaper.

Can You Finish An 80 Lower Without Jig?

No. You cannot finish an 80 lower without a jig designed to complete 80 percent lower receivers. Without an 80 lower jig, attempting to accurately drill out the fire selector, trigger, or hammer pin holes would prove to be very difficult if only done by hand if not impossible. The same could be said for milling out the trigger control group pocket.  The only exception would be if you own a mill, or a CNC machine. Manual mills are how AR15 lower receivers were made in the past before the CNC machine, which is how they’re finished now. And many companies, top manufacturers in the industry, make their lowers from 80% lower receivers also, as it’s easier for them to purchase the AR15 receivers mostly completed. Of course, if you own a manual mill, or a CNC machine, you’re probably not shopping for an 80 lower jig to finish your 80 lower!
