KAK Industry AR-15 LPK Spring Kit – Replacement Springs for AR-15 Lower Parts

The KAK Industry AR-15 LPK Spring Kit provides all the springs needed to rebuild or complete an AR-15 lower parts kit. This kit is designed for armorers and builders who need to replace worn springs or complete a partial lower parts build without buying a full LPK. Each spring is manufactured to mil-spec dimensions to ensure reliable function in standard AR-15 lower receivers.

Springs are made from heat-treated carbon steel with a phosphate finish for corrosion resistance. Installation requires basic armorer's tools and familiarity with AR-15 lower assembly. This is a drop-in replacement for standard AR-15 trigger groups and lower receiver components.
