The KAK AR-15 Basic Build Lower Parts Kit (brand part no. AR15-LP-KT-02) supplies the internal components needed to complete a stripped AR-15 lower receiver. KAK Industry was founded and incorporated in 2011 by Kurt Kosman to address a gap in the market for quality, American-made AR components at affordable, sustainable prices. A basic build kit like this covers the fire control components, springs, pins, and detents a builder needs to go from a stripped receiver to a functioning lower, without a stock or grip already attached. For a first AR-15 build or a lower rebuild, having a complete, matched kit removes the guesswork of sourcing dozens of small parts individually.
