CMMG LPK 556 BLK – AR-15 Lower Parts Kit

The CMMG LPK 556 BLK is a complete lower parts kit for building or refurbishing an AR-15 platform rifle. This kit includes all the small parts needed to complete a stripped lower receiver: trigger group, hammer, safety selector, magazine catch, bolt catch, and all associated springs, detents, and pins. It's a solid choice for home builders or gunsmiths looking for quality components at a fair price, or for replacing worn or damaged parts in an existing lower.

Constructed from mil-spec components with a black finish, this kit is designed for drop-in installation by anyone with basic AR-15 assembly knowledge and standard gunsmithing tools. Most builders can complete installation in under an hour with a punch set, hammer, and patience—especially when managing small detents and springs. No specialized machining or fitting required.
