Important Update Regarding ATF Regulations and Easy Jig Sales

Due to recent changes in ATF regulations, 80% Arms can no longer sell or support jigs directly.

Support and Warranty Service: For all Easy Jig customers, modulusarms.com will now handle support. Modulus Arms will honor warranty services, provide technical support, and offer replacement tools and parts for all Easy Jig products.

Manufacturing and Sales: While Easy Jigs will continue to be manufactured by 80% Arms, all sales must now be conducted through our independent dealers to comply with the new regulation. We are no longer permitted to sell jigs or distribute manuals via our website under these new ATF rules.

Legal Challenges: We are actively challenging this government overreach in court. We are optimistic about a favorable ruling from the Supreme Court in 2024, as both the District Court and the 5th Circuit Court of Appeals have ruled decisively in our favor.

Availability through Dealers: In the meantime, our jigs are still available through our dealers, despite our inability to sell them directly.

We appreciate your understanding and continued support during these changes.

 

With a revolutionary 80% lower jig, comes a revolutionary end mill. Our all-new Speedmill™ with SpeedCoat for the Easy Jig® Gen 3 is the most efficient and effective milling system on the market today. Pairing our top-of-the-line end mill with our new heat-shrink tool holder, the combination virtually eliminates deflection and total runout.

It features:

  • Solid Carbide End mill
  • Optimized Fluting for Aluminum
  • Extremely Rigid Support
  • Direct-Thread to your Router
  • SpeedCoat™ Zirconium based coating specifically formulated to offer superior lubricity and longer tool life when milling aluminum
  • Longer Lasting, Averaging 7-12 Lowers per bit for Experienced Users
  • Made in the USA

We have made this a direct-thread system, to make sure you have the most solid lock-up and repeatability when it comes to milling your lower to CNC level results. Because of this feature, each router will require a different size selected when you order.
