Our gold-standard 80% lower holds a special place in our heart. This hugely popular, affordable 80% lower is one of the first products we ever brought to market, and with it, we helped develop an entire industry of at-home gunsmithing.

Proudly forged in the USA from mil-spec 7075 T6 aluminum and featuring pre-engraved FIRE and SAFE markings, this lower’s ready for final machining and assembly with the aid of any of our 80% lower jigs.

Buying, owning, and machining this 80% lower into a stripped lower receiver is 100% legal in all 50 states. You do not need to work with an FFL dealer or have a background check completed to buy or machine this lower into a functional receiver. If you can legally own a gun, you can build this lower!

Check out the latest and most advanced router-based 80% lower jig on the market, the Router Jig Extreme by Modulus Arms! Finally you can stop looking for a completely universal jig! Sure, it'll mill the standard AR-15 and AR-9 sized 80% lower receivers.  But you can also stop wondering whether it'll accept the DPMS gen 1 patterned LR-308 lower or the Colt patterned AR-10 lower.  It does both.  Now you can do all four types of lowers without having to buy an expensive jig conversion kit! On top of that, this jig will blast through your lowers in record time!

And the Router Jig Extreme is jam-packed with features. Modulus Arms took their original router jig and upgraded the hell out of it. The Router Jig Extreme will blow through your 80% lower and leave a CNC machine quality trigger pocket that looks like it was professionally done. The Router Jig Extreme uses built in trigger pocket template guide tracks. All its drilling surfaces are hardened steel too, so none of them will ever wear out. It’s got built in depth guides, so you don’t even worry about measuring anything. Just keep adjusting your router’s SpeedMill ™ bit to each new milling depth, and repeat until you’re done.

The Router Jig Extreme's side plates are and inch and a half thick. 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 out of your way while you work. 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.
