PLEASE NOTE: THE TOOLING FOR THE MODULUS ARMS ROUTER JIG EXTREME DEPENDS ON THE BRAND AND MODEL OF YOUR ROUTER.  PLEASE SEE THE “SIZING CHART” BELOW TO SELECT THE CORRECT TOOLING OPTION.

Introducing the Modulus Arms Router Jig Extreme, the latest and most advanced router-based 80% lower jig on the market!  The jig is completely universal, meaning not only can it mill AR-15, AR-9, and LR-308 80% lowers, but it also accepts AR-10 80% lowers as well!  You used to have to worry about whether your jig was made to accept the LR-308 DPMS gen 1 pattern or the AR-10 pattern from Colt.  Well no more!  Now you can do all four types of lowers without having to buy an expensive jig conversion kit!  This jig does it all and in record time!

This 80% lower jig is loaded with features too.  Based on the original Modulus Arms router jig, the upgraded Router Jig Extreme’s performance will mill your trigger pocket accurately and with professional CNC machine quality.  The Router Jig Extreme uses built in trigger pocket template guides, and with all its surfaces being hardened steel, you can be sure no parts will ever wear out.  It’s got built in measuring gauges, so you don’t have to bother bringing extra measuring tools to the table.  Simply adjust your router’s SpeedMill ™ bit to the next notch and repeat for additional depths until you’re done.

The Router Jig Extreme has 1.5-inch thick side plates whose drill holes come lined with ultra-hardened steel bushings, to help ensure straight and perfect alignment when drilling the holes for your safety selector and trigger pins.  This jig also has a shop vac attachment to help keep the aluminum shavings clear and out of your way while you work.  Plus, the entire assembly is self-centering and has no-touch side plates, meaning you get the most accurate results and perfectly aligned trigger pocket and side hole drillings.

To learn more about how awesome this jig is and how easy it is to use, check out the instruction manual here.

Besides the trademarked SpeedMill ™ end mill bit, the tooling comes with all the drill bits you need to finish your 80% lower in no time.
