James Madison Tactical has made a great name for themselves in the 80% Polymer/Composite AR Lower market by making what I would say is the best 80% Polymer / Composite lower out there. They went to great lengths to strengthen the necessary areas that have been failure points on other polymer lowers in the past but the material itself also makes a huge different. The guys at JMT have spent most of their career manufacturing amazing $1,000,000 kit Jet planes called the ViperJet that you can build at home. They then took their expertise in AERO Space polymers that are strong enough to be used in airplanes and used that same material to build a high quality, reinforced AR15 80% lower. The Gen 1 lowers were fantastic but now JMT has upped their game with the Gen 2 lower adding lots of enhancements.
Some of the enhancements are to further strengthen the design but a couple are cosmetic and they look awesome. One such upgrade is the webbing pattern on the magwell that is reminiscent of the PMAG design. The other is they removed the large “JMT” logo from the side of the magwell and replaced it with a much smaller logo on the Pivot Pin Spring Housing. Oh yeah, the machining jig you need to complete the lower comes FREE with the purchase every lower and the price is just $99.95 each. Take a few minutes to read the official press release below and check out the pics of the new lower. Purchase links are at the bottom.
