The patented Easy Jig® Gen 3 Multiplatform™ replaces the Gen 2 as the world's easiest to use, fully universal, 80% lower jig capable of finishing AR-15, AR-9, AR-45 and DPMS gen 1 pattern .308 80% lower receivers without the need for any additional adapter pieces. The jig converts between AR-15 and .308 by quickly adjusting the rear buffer support, making it easier than ever before to mill any platform you desire.

The Easy Jig® Gen 3 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, and then the revolutionary Easy Jig Gen 2. We thought through every possible detail to improve the user experience with Easy Jig® Gen 3 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 is the first jig in the world to account for tolerance variances across any possible lower, allowing them to mount at their true datum points. An all-new mounting surface with our "Trident" front pin completely eliminates yaw, pitch, and roll of the lower while in the milling process. We invite side by side comparison to any other 80% lower jig on the market, nothing else compares.
