With careful engineering, we were able to serve our customers with a single Jig to complete their M1-80 AR 10 and M1-80 AR 15 80% lower receivers. This is the kit of all kits. If you are planning to get into custom 80% rifles, this is the kit you need.

 

Even though our jig is called "Universal", it may not be compatible with all other 80% lower receiver brands. The name “Universal” is used simply to imply that one jig will finish both M1 Machining AR 10 and AR 15 lower receivers.  This Jig is not compatible with Forged Lower Receivers.

 

Key features of our Universal Milling Jig for both AR 15 & AR 10 80% lower receivers:

Easy and Fast Assembly: The router template and drill template are now held down with ONLY SIX SCREWS! This makes changing configurations for milling and drilling a breeze.

Universal Compatibility: Use of standardized upper dimensions to locate and center the Jig results in universal compatibility and more accurate machining.

Safer and Faster: Universal design allows for safer and faster milling of 80% lower receivers without having to keep many different jigs and getting confused between different parts and models.

Professionally Engineered Design: The M1 Machining Lower Receiver Jig is designed by a team of mechanical engineers with decades of experience and CNC machined to tight tolerances. And because we look for to increase your friendly shopping experience with everything you may need for your custom rifle build. M1 Machining would like to thank you for your support and for giving us the opportunity to earn your business. Last and not least, Made in USA by American hands!

Nice jig Review by Jimmy

A friend bought one of the M1 80% .308 lowers and asked if I could help guide him through the milling process. I have two other .308 jigs that from two different companies that did not work with this lower, so I went halves on this M1 jig with him.

I ordered on January 9th expecting it to come in a few weeks. After a few weeks later and no email reply, I called M1 and spoke to one of the employees who stated they went to SHOT and while a few of their employees stayed behind to work on orders but their machine went down and had to be re-calibrated when they returned.

I received the jig this week and my buddy came over with his M1 lower. Double wow! This lower is specific for their lower but I must say it is a well thought out jig. This jig keeps the lower rock solid. It's nicer than the other two jigs I have.

My friend took the cuts slow and easy and the lower cut came out nice. I don't have any experience with billet so I admit this was amazing to see my friend do his first lower with no problem.

I plan on buying an M1 lower and upper myself. Every plate is nicely machined and bolts up evenly. (Posted on 2/5/2017)

The only thing I would add & did to mine was a drilled slots at the proper depth as a guide for the trigger pocket & the rear pocket area to make it quicker to set up (Posted on 10/10/2016)

Company does not answer Emails timely. Fixture works, but when drilling side holes, be careful not to damage other side of fixture when drill goes through 80% lower. Good value for the sale price. Tomcat (Posted on 9/3/2015)
