Description
Stage 5 AR15 Complete Lower Parts Kit With Phosphate Internals
The Stage 5 AR15 Lower Parts Kit gathers a full set of mil-spec components for completing a lower assembly in a single purchase. With phosphate-coated internals and parts made in the USA, this kit serves builders finishing a stripped AR-15 lower receiver as well as gunsmiths stocking the bench with springs, pins, and detents.
Because lower parts kits include trigger group components, confirm the contents match your specific build and intended controls before assembly. If you only need select pieces, compare the Stage 3 kit without a fire control group or browse standalone trigger parts.
