James Madison Tactical AR-15 80% Lower with Jig

The best just got better! James Madison Tactical is proud to introduce the new Gen2 AR-15 80% lower receiver. JMT is constantly evolving to deliver the ultimate lower in the industry. The decision to refine the cosmetics to their already rugged JMT composite / polymer lower, while at the same time taking the liberty to beef up existing strengths, truly makes the JMT lower even more substantial. JMT invites you to take a look and compare them to the competition. After doing so, JMT is completely confident you will choose them.

Extended upper fire control box sections.
Upper left magazine well box section.
Webbed magazine wells L & R side (matched for MagPul) magazines.
Extended bolt release roll pin posts.
New JMT Gen2 logo markings.

After much research in polymer AR-15 lowers, JMT created its own formula of hybrid polymers and fibers with additional reinforcements in high stress areas to bring you the best AR-15 lower on the market today. All of the JMT polymer 80 lowers are engineered to Mil Spec tolerances and because it is fashioned from extremely durable fiber polymer materials there are no concerns about corrosion as you may find in aluminum AR-15 lowers.
