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.

 

DESCRIPTION:

If you're looking for a one-stop shopping experience, this is for you. Packaged to be everything you need, and nothing you don't. No measuring spindle sizes or figuring out the optimum bit speed on your router, we have it all covered for you. Keeping in tradition with making the easiest router-jigs on the market, we've also made it as easy as possible to get started. 

The threaded bolt catch screw that is required with our .308 lowers does not come with our lower. However, it does come standard in our .308 Lower Parts Kit.

This Kit Includes:
