The CMMG Lower Parts Kit 556 (without grip and fire control group) is specifically designed for AR-15 builders and gunsmiths who prefer to source trigger groups and pistol grips separately. This lower parts kit includes essential hardware, springs, pins, and retention components necessary to assemble a functional lower receiver, excluding the fire control group and pistol grip.
Every component in the kit is intended for compatibility with standard AR-15 platforms, allowing builders to customize their firearms according to specific requirements and budget. The modular approach of this kit is ideal for those who already have a preferred fire control group or plan to upgrade to a match-grade trigger later in the build process. The kit is built to meet Mil-Spec standards, ensuring reliability and performance.
This lower parts kit is perfect for builders completing AR-15 builds from scratch, armorers performing lower receiver assembly during maintenance, and tactical enthusiasts restocking inventory after component upgrades. Whether for a patrol rifle, training platform, or competition build, the CMMG LPK 556 provides quality components that allow for precise control over the final trigger quality and grip ergonomics.
