Product Details

Shipping Status: In Stock

The patented Easy Jig® Gen 2 is the world's easiest to use, fully universal, 80% lower jig capable of finishing AR-15 and AR-9 lowers. Easy Jig® Gen 2 is the culmination of our years of experience gained from manufacturing the world’s first router jig and the best selling 80% lower jig in history, the Easy Jig® Gen 1.

We thought through every possible detail to improve the user experience with Easy Jig® Gen 2 and took into account hundreds of suggestions from our customers. No detail was too small to be overlooked. The result is quite simply the finest 80% lower jig ever produced. This may not be the absolute cheapest jig on the market, but it is arguably the very best. We invite side by side comparison to any other 80% lower jig on the market, nothing else compares.

Our AR-15 / AR-9 only version of Easy Jig® Gen 2 has all the amazing features of the Easy Jig® Gen 2 Multi-Platform, except it does not fit .308 lowers. If you want to complete AR-15, AR-9, and .308 in the same jig, Easy Jig® Gen 2 Multi-Platform is the best choice. The AR-15 / AR-9 only jig cannot be retrofitted to accommodate .308 lowers.

I tried the gen. 1 jig. It was a LOT more work. The gen. 2 is almost too easy. You need to remember to be patient and not try to cut too fast. listen to your mill bit. If it starts to scream at are going too deep or too fast. I did a 9mm and a 5.56 and they both turned out great.

Works as advertised!!!

If you follow the directions and go slow it works perfectly. You can't tell the difference between what I milled with the jig and what is out there commercially. A very well made product.

Great Jig

Bought a gen 2 easy jig, along with the tool kit and 3 billet lowers. Very easy to use, and overall a great system. I'll likely have a lower for every day of the month before the end of this.

Love it!

From the moment I opened the box I knew this was a stellar product. Superior materials and extremely well engineered. The instructions are very comprehensive, as well. Looking forward to milling several lowers in the future.
