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.

Feast your eyes upon the Modulus Arms Router Jig Extreme, the market's latest and most advanced router-based jig! Finally there is a one-size-fits-all, completely universal jig! Of course it'll still mill the standard AR-15 and AR-9 sized 80% lower receivers. But what about 80% lowers in the .308 caliber?  Got a DPMS gen 1 patterned LR-308 lower?  Great!  What about a Colt patterned AR-10 lower?  No problem!  This thing does it all!  Now you can do all four types of lowers without having to buy an expensive jig conversion kit! And the icing on the cake is, this jig can mill out 80% lowers in record time!

And the Router Jig Extreme is chock-full of features. Modulus Arms took their original router jig and upgraded it like crazy. The Router Jig Extreme will take your 80% lower and give you professional looking results with a CNC machine quality trigger pocket. The Router Jig Extreme uses built in template guides for the trigger pocket, so you don't have to worry about getting the right dimensions on yours. All its drilling surfaces are hardened steel too, so none of them will ever wear out. It’s got built in milling depth guides, so you don’t even worry about measuring anything. Simply adjust your router’s SpeedMill ™ bit to the next depth after each pass, and rinse and repeat until you’re done.

The Router Jig Extreme's got inch and a half thick side plates. The drill holes are lined with ultra-hardened steel bushings too, so you'll get straight and perfect alignment with your safety selector and trigger pins. It's also got a shop vac attachment to help keep the shavings and debris swept out of your way, so you can see what you're milling. Plus, the Router Jig Extreme's design is self-centering, with no-touch side plates, so you get the most accurate results and perfectly aligned trigger pocket and side holes possible.
