The KAK Industry AR-15 Missing Parts Kit (KAK part no. AR15-LP-KT-04) bundles the small detents, springs, and pins that commonly get lost or damaged during an AR-15 lower parts kit build. Rather than buying a full replacement lower parts kit when a shooter is only missing a handful of small components, this kit fills in those gaps at a fraction of the cost. It’s a practical addition to a builder’s parts bin for anyone assembling multiple AR-15 lowers or replacing small components that got dropped, lost, or worn during a previous build.
