Description
The James Madison Tactical JMT Gen-2 is a polymer 80% lower receiver. It uses reinforced polymer construction with a black finish for corrosion resistance. The design includes an integrated trigger guard and reinforced takedown lugs for structural integrity.
This lower receiver is compatible with standard AR-15 upper receivers and mil-spec parts. It accepts standard AR-15 triggers, grips, and buffer tube assemblies. The polymer alloy meets SAE AMS-S-751 specification for durability and dimensional stability.
The lower ships with a machining jig for completing the 80% receiver. It requires milling of the fire control group pocket and selector switch hole. No FFL transfer is needed as this is an unfinished receiver.
Tolerances are within ±0.003 inches for critical dimensions. Weight is 4.7 ounces. The Gen-2 version improves on previous models with thicker wall sections at stress points.
