James Madison Tactical is proud to introduce the new Gen2 AR-15 80% Lower Receiver with Jig Kit. 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. The polymer 80% lower receiver for your AR-15 platform is engineered and manufactured by James Madison Tactical in the USA. This is not your average polymer 80 lower, in fact, it is fully engineered using current finite element structural analysis for reliable, long-term high performance. 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, that you may find in aluminum lowers. The AR-15 80% Lower Receiver is designed, specifically, for a high level of interchangeability with other Mil-Spec AR-15 parts and accessories on the market today. This is achieved through current technology and computer aided manufacturing processes combined with exacting quality control procedures. The operations left to be completed to complete your JMT AR-15 80% lower are as follows: fire control group, trigger pin, hammer pin, trigger slot and the safety selector hole. This is a not an FFL item. This is not a complete receiver and still requires machining to be done.
