The KAK Industry KF-15 complete lower receiver in Black (brand part no. 801-0604-002) ships fully assembled with a lower parts kit installed, but leaves the stock choice to the builder rather than locking in a factory-installed option. KAK Industry builds the KF-15 as a mil-spec-pattern foundation for an AR-15, so any standard 6-position or pistol-brace buffer tube and stock or brace will fit. Because the parts kit is already installed, this lower saves the builder from sourcing and assembling trigger, hammer, and small parts individually, while still leaving the final stock choice open. Among the complete lowers in the AR15 lowers category, the KF-15 is built for shooters who want an assembled lower without committing to a specific stock.
