80% Lower Jig (Easy Jig Gen 2 AR15/AR9) with Tooling:

 A 100% Universal 80% Lower Jig

Now compatible with AR-9 lowers and all AR15 lowers, the Easy Jig Gen 2 now effortlessly centers your lower which guarantees your lower will come out perfect, even with customized designs or cuts. It’s been battled tested to work with the top 23 of the most common residential, compact routers. It is also the only jig that works with full-size routers for even quicker machining. Want to use a hand drill? Optional hardened steel stabilizers will help keep things nice and tidy.


This AR-15 / AR-9 only version of the Easy Jig Gen 2 can do everything that the Easy Jig Gen 2 Multi-Platform does, with the exception that it does not fit .308 lowers. If you are interested in completing AR-15, AR-9, and .308 lower receivers using the same jig, the Easy Jig Gen 2 Multi-Platform is your best option. This AR-15 / AR-9 only jig cannot be upgraded or modified to complete .308 lowers. Click here to view the Easy Jig Gen 2 Multi-Platform, the combined AR-15 / AR-9 / .308 jig.


Fast and Too Easy

The Easy Jig Gen 2 is fast as they come. Build times have been recorded as low as 30 minutes to finish a lower with the Gen 2, compared to 45 minutes – 1 hour+ with other jigs. The patented built-in measuring gauges take all the uncertainty out of the build, and now all you need to do is drill one hole before milling.
