Piecing together that LR-308 rifle is easy and affordable with JMT’s Gen 2 Polymer 80% .308 Lower. This ultra-light receiver shaves critical weight off your newly minted rifle, improving performance and comfort.
This lightweight, reinforced receiver was tested, re-tested, and made to take the brute force of any .308 rounds you chamber. JMT took their existing polymer-fiber material and upgraded it to be tougher, harder, and stiffer. It can handle rapid fire, high heat, and high impacts with utter reliability.
This 80% receiver is compatible with any DPMS-pattern .308 components and features mil-spec fittings. Included is the 80% jig required for drilling the hammer, trigger, and safety lever pin holes, as well as an easy-to-follow template for cutting the main cavity to install your LPK.
