80 Lower Jig Guide: Easy Jig Gen 2 Multi platform VS 5D Tactical Router Jig Pro VS Modulus Arms Router Jig Extreme

80 Lower Jig

The 80 percent lower market is heating up as more and more makers pump out some wicked cool 80% lower jigs. The task of machining your first (or twelfth) 80% lower will continue to get easier and more enjoyable – but which jig should you pick? We’re stacking up three of the most popular 80 lower jigs: The Modulus Arms Router Jig Extreme, the Easy Jig Gen 2 Multi-Platform Edition, and the 5D Tactical Router Jig Pro. The former is a newcomer to the game while those last two are crowd favorites.

So, which should you pick? Let’s help.

80 Lower Jig: Easy Jig Gen 2 Multiplatform

The Easy Jig Gen 2 – Most Popular 80% Lower Jig, Easiest for Beginners

The Easy Jig Gen 2 has been a top contender on our parts lists for some time, and for good reason. It’s one of the best-selling 80% lower jigs available on the market. Easy Jig keeps the competition stiff by making the Gen 2 compatible with any AR-9, AR-15, or DPMS Gen .308 lower like Modulus Arms’ Router Jig Extreme.

Features:

  •         Integrated measuring guides
  •         Machining time less than 30 minutes
  •         Switches from AR-15 to .308 in seconds
  •         Includes shop-vac buffer tube attachment for easy clean-up
  •         Hardened steel construction
  •         No-touch guides and contact-free router plate design

The Easy Jig Gen 2 costs a bit more (around $290) than a raw Router Jig Extreme, but it comes with a nice matte gray finish atop its hardened steel construction – and it includes all the drill bits and end mill bits needed for machining. In the end, the Gen 2 wins on cost by a few bucks compared to the Router Jig Extreme, and setup is a little more convenient thanks to the included hardware. If you want to save a little cash and get an all-in-one kit with a minor trade off (slightly more drilling), then this is the jig for you.

80 Lower Jig: Modulus Arm Router Jig Extreme

The Modulus Arms Router Jig Extreme – Fastest & Lowest Cost 80% Jig

Modulus Arms’ new Router Jig Extreme claims to be the fastest-to-use and highest quality 80% lower jig available on the market. While those are tall claims to make, Modulus Arms offers up a no-questions-asked, 100% money back satisfaction guarantee – a full refund if you don’t love the thing, in their own words. But is it true?

Features:

  •         Claimed fastest machining time (15 minutes or less)
  •         Compatible with AR-15, AR-9, and .308-chambered lowers
  •         Hardened steel construction
  •         Proprietary guide pins guarantee no end mill-to-jig contact
  •         Heat-treated end mill holder increases rigidity and accuracy compared to standard carbide
  •         1.5” thick side plates for stability during machining
  •         Only one hole required for machining

Why the Router Jig Extreme Rocks

A couple of things jump out at us from the Modulus Arms Router Jig Extreme, but we love that sub-15-minute machining time. If you’re the type to obsess and tinker by doing a task over and over, the Router Jig Extreme is the best choice for that speed and efficiency.

Because the Jig Extreme is so fast, we’d recommend this for veteran 80% lower guys and gals – but we’d still recommend it to newcomers for its easy drilling requirements. One hole is a helluva lot easier to drill for your first lower than three, four, or more.

80 Lower Jig: 5D Tactical Router Jig Pro

The 5D Tactical Router Jig Pro – Premium 80% Jig, Fastest, All-Inclusive Kit

5D Tactical cranks up the heat (literally) by offering up what we wager to be the most rugged and heavy-duty 80% lower jig of the three on our list. Of course, the 5D Jig would only qualify as a competitor on our list if it had all the fixings: quick machining times, a big, solid foundation to work on, guide plates, universal fitment – and it certainly does.

Features:

  •         Claimed machining time of less than 15 minutes
  •         Requires just one pilot hole to be drilled
  •         Patented ReadyMILL bit is claimed to be strongest end mill bit
  •         Shop-vac attachment for easy clean-up
  •         Guaranteed to fit any AR-15, AR-10, .308, and AR-9 lower
  •         1.5” thick plates with hardened steel construction
  •         Guide pins to prevent milling and drilling contact

The 5D Jig also boasts some other cool features to ensure accuracy and reliability. The 5D Jig uses your receiver’s takedown pin and buffer tube to secure your 80% lower to the jig, guaranteeing correct fitment with your fire control group and upper receiver once assembled.

Although more expensive than the Easy Jig Gen 2 and Modulus Arms Router Jig Extreme, the 5D Tactical Router Jig Pro boasts all the pros of the former with no tradeoffs to speak of. It machines as fast as the Modulus Arms and it contains the same universal fitment, ease of use, and included hardware like the Gen 2.

If you want to shell out the most cash for a premium 80% lower jig that’s a cut above the rest – the fastest, strongest, most reliable, most universal, and easiest to use – then the 5D Tactical Router Jig Pro is the jig for you.

If you don’t want to spend premium cash but you want speed, stick with the Modulus Arms Router Jig Extreme. If you want an all-in-one kit that’s easy to use with plenty of tutorials and guidance for first-timers, go with the Easy Jig Gen 2.
