KAK Industry AR-15 Basic Build Lower Parts Kit

The KAK Industry AR-15 Basic Build Lower Parts Kit is the entry-level "basic build" LPK ready to complete your AR-15 lower receiver build. Designed for builders who plan to supply their own trigger group, this kit provides the standard mil-spec lower internals used to finish out a stripped or partially built AR lower.

Among the mil-spec components included in this basic build kit are the magazine release, magazine release spring, and magazine release button. The kit is built around the standard AR-15 lower pattern, making it a straightforward drop-in option for your AR-15 lower build.

KAK Industry packages the basic build LPK in their signature yellow bag for easy bench-side identification. Whether you are assembling a first AR-15 from a stripped lower, refreshing worn internals on an existing build, or keeping a bench-ready spare set on hand, this basic build lower parts kit delivers the core mil-spec components for your AR-15 lower build.

Note: This listing is for the lower parts kit only. The lower receiver, trigger group, buttstock, pistol grip, upper assembly, and other build components are sold separately.
