Top 2 80 Lower Jigs of 2019

With tax season upon us, it’s time. Yes, it is time to anger the spouses and start that 80% lower AR-15 project! We’re excited you could join us – but what 80 Lower Jig should you opt for? With so many available (and so many calibers to pick from), it can be tough deciding.

Here are the top 2 80 Lower Jigs of 2019!

#1 80 Lower Jig: Easy Jig Gen 2 Multi-Platform 80 Lower with Tooling

This may come with little surprise, but Easy Jig continues to reign supreme in 2019 as King o’ the Jigs with their Easy Jig Gen 2. This multi-platform 80 Lower has been winning hearts of minds of black rifle builders for quite some time – few competitors have put their best foot forward thus far to challenge it.

Easy Jig Gen 2 Multi Platform with Tooling (AR-9 / AR-15 / LR-308)

Why is the Easy Jig Gen 2 so great?

  •         Completes any lower in 30 minutes!
  •         90% less drilling that competing jigs
  •         No disassembly required to start a new lower
  •         Convenient shop-vac attachment for clean-up

The Easy Jig Gen 2 is perhaps the most convenient lower if you’re interested in pumping out stripped receivers one-after-the-other. This is one of few jigs that requires no disassembly. But Easy Jig also took customer feedback and they’ve updated the Gen 2 with stronger features and better materials:

  •         All drilling surfaces are made of hardened steel
  •         Side plates are now also made of solid steel
  •         No-touch router plate prevents tool-on-plate contact

The Gen 2 is also foolproof, integrating self-guiding plates and drill depth guides, so you don’t need to measure or calculate anything yourself. Whether you want to build an AR-15, an AR-9, or a DPMS Gen 1 .308 lower, the Easy Jig Gen is compatible!

#2 80 Lower Jig: Polymer80 G150 Phoenix2 80% Lower with Jig and Tooling

This is an interesting entrant to the 80 lower market for 2019. Polymer80 is one of the big names in the build-a-gun market, largely thanks to their successful Glock frames and jig kits. They’ve done it again by bringing to market one of the best (in our opinion) polymer AR-15 80% lowers – and the lower includes the jig and tooling!

The G150 Phoenix2 costs literally pennies compared to other jigs and lowers, but is it a quality lower? Polymer80 took the time to test this new lower and re-design repeatedly, until they created a lower worthy of the AR-15’s own reliability and ruggedness.

G150 Phoenix Polymer 80% Lower

The G150 Phoenix Polymer 80% Lower is one of the most affordable 80% lowers you can buy.

  •         Weapons-grade polymer construction
  •         Solid core design for added strength
  •         Stiffened mag wells and reinforced buffer tube housing
  •         No-thread pistol grip reinforces trigger area

The lightest lower on the market

The G150 Phoenix2 has already been proven in customer builds – but why should you consider it and its jig? For starters, this new lower weighs less than one pound! This is the 80 lower you want for your AR build if you’re aiming for an ultralight weapon.

The included jig is also 100% universally adaptable with any other lower, even aluminum lowers. The included tooling is also compatible, so you’re set for future builds and you technically get a lower included with this jig by default – something no other jig offers at this time.
