Easy Jig® Gen 4 Multi-Platform Jig with Router, Tooling & 5 Lowers
The Easy Jig® Gen 4 is the next evolution of the jig that started it all.
Built from years of real-world manufacturing experience, customer feedback, and hard-earned improvements, Gen 4 takes everything builders loved about our previous Easy Jig® systems and pushes it even further.
This is our most advanced, most versatile, and easiest-to-use jig yet, designed to help you finish multiple 80% lower platforms with one all-in-one system.
The patented Easy Jig® Gen 4 Multi-Platform™ gives builders one jig for AR-15, AR-9, AR-45, and DPMS Gen 1 pattern .308 lowers. No extra adapter plates. No complicated setup. No buying a different jig for every platform.
Adjust the rear buffer plate, lock in your lower, and start cutting. Gen 4 also includes a mil-spec M16 fire control group pocket cut, one of the biggest upgrades customers have been asking for.
Truly Universal
One jig. Multiple platforms. Zero nonsense.
The Easy Jig® Gen 4 is designed to work with:
- AR-15 lowers
- AR-9 lowers
- AR-45 lowers
- DPMS Gen 1 pattern .308 lowers
It converts between AR-15 and .308 platforms in seconds by adjusting the rear buffer plate, with no additional adapter pieces required.
Router, Tooling & 5 Lowers Included
No scavenger hunt. No guessing what works. No ordering half the setup from three different places.
This package includes the router, required tooling, and 5 80% lowers of your choice.
Fast, Simple, and Built for Real Builders
The Gen 4 system was designed to make the process easier from start to finish.
- Drill only one pilot hole with a handheld drill before milling
- No drill press required
- Built-in measuring gauges mean no extra measuring tools are needed
- Lowers can be inserted or removed in under 10 seconds
- No sidewall disassembly required
Less setup. Less guessing. More time building.
Built to Last
The Easy Jig® Gen 4 was engineered for durability, repeatability, and long-term use.
- Premium bearing-supported end mill design prevents the end mill from contacting the jig
- No wear surfaces from the end mill riding against the jig body
- Hardened steel drill guide and sidewall bushings
- Sidewall bushings are over 1” long for added support and strength
This jig was built to take abuse and keep going.
Built With Confidence
The Easy Jig® Gen 4 is backed by our lifetime warranty against manufacturing defects on both our jigs and lower receivers.
Whether you are building your first 80% lower or adding another platform to the bench, Gen 4 gives you the tools, flexibility, and confidence to do it right.
No FFL required. Federal, state, and local laws may apply.
