The LMT 5.56mm lower parts kit with trigger group gives you the foundation that goes into LMT Defense's combat-proven rifles—now available as a standalone build component. Whether you're completing a precision rifle, a dedicated patrol gun, or a reliable duty carbine, this kit delivers the same mil-spec quality and attention to detail that professional gunsmiths and serious shooters depend on. Built entirely in the USA, it's engineered to handle the demands of the range, the field, or the job.
This is a complete lower parts kit that includes everything needed to assemble a functioning lower receiver, with the critical advantage of a professional-grade trigger group already in the package. You get the LMT AXLE two-stage trigger—the same trigger system that ships in LMT's factory rifles—which means no hunting for a separate trigger, no compatibility guessing, and no compromise on the firing control you get out of the box.
What's included covers all the hardware and functional components: trigger guard and magazine catch assemblies for reliable feeding and ergonomic control, bolt catch and pivot/takedown pin assemblies for field stripping and operation, buffer retaining hardware to keep your recoil system in place, and an ambi selector that lets you run the rifle naturally whether you shoot right- or left-handed. Build with confidence knowing these parts work together as a system, not a collection of generic substitutes.
