KAK Industry Lower Parts Kit Features The KAK Industry Lower Parts Kit supplies everything needed to finish out a stripped AR-15 lower receiver except for the pistol grip and trigger guard letting builders choose those two parts separately to match their preferred look or feel. The kit includes a complete fire control group along with a bolt catch and magazine release all manufactured to mil spec dimensions for guaranteed fit and function. Every spring detent pin and miscellaneous small part needed for assembly is included so builders are not left hunting for a missing component mid build. Black oxide coated springs are used throughout for added corrosion resistance over the life of the build. KAK Industry was founded in 2011 specifically to address a gap in the market for quality American made firearm components sold at an affordable sustainable price point. This Lower Parts Kit reflects that mission giving builders a complete reliable set of internals manufactured one hundred percent in America rather than imported parts of unknown origin. Pairing this kit with a buffer assembly kit completes everything needed to finish a functional AR-15 lower receiver. This Black Lower Parts Kit is a straightforward dependable choice for any AR-15 build where the builder already has a grip and trigger guard in mind.
