James Madison Tactical Gen 2 80% Polymer Lower and Jig
The JMT 80% Carbon/long Fiber/polymer lower receiver is not to be compared with any other polymer lower on the market today. JMT has incorporated new material technology and manufacturing processes for enhanced durability, strength and reliability. The JMT 80% lower also comes with a specially designed 3-piece machining jig with every order. This allows the user to machine the JMT 80% polymer/composite fiber lower receiver with ease and precision using simple tools.
The first thing users will notice is the JMT 80% lower receiver looks beefed up from the outside and rightly so. JMT has managed to reinforce traditionally weak points found on other lower receivers offering the user a stronger lower receiver while keeping all of the required Mil Spec areas and attach points within Mil Spec tolerances. This permits smooth operations using a wide variety of Mil Spec and aftermarket accessories.
An enhanced mag well allows for use of many different magazines. No more concerns about whether your magazine is going to release when you push the magazine catch button. The JMT 80% polymer/fiber lower receiver features the latest in polymer/composite fiber technology along with sound engineering and (FEA) structural analysis. Reinforced longerons that run full span along the fire control pocket, over a molded metal threaded insert for pistol grip screw, reinforced butt stock mount, enhanced oversize trigger guard, reinforced flared mag well, forward magazine finger grate, enhanced gusseted forward upper receiver tabs, This is what makes the JMT 80% lower receiver superior to all others.

Take down pins need tool or bullet tip to reach and push in. Top area had slight amount that needed to be trimmed to allow rear take down pin holes to line up.
Video from JMT is for previous/different version and different, have to research and hope if it is your first one.
Only $15 less than Anderson lower and metal jig to do same thing. if doing 2 aluminum is cheaper. (Posted on 9/23/2016)
