Stage 1 AR15 Lower Parts Kit for Builders
The Stage 1 AR15 Lower Parts Kit gathers the foundational springs and detents needed to complete a lower receiver, making it a practical starting point for a custom AR-15 build. These are the small internal parts that frequently go missing or get lost during assembly, so a dedicated essentials kit helps builders stay organized and keep projects moving. The components are proudly made in the USA.
This kit suits AR-15 platform builds whether you're assembling your first lower or restocking your workbench. Before installation, verify that the included small parts match your specific lower controls and fire control configuration. Keeping spares of easily lost buffer retainer springs on hand reduces downtime.
Builders needing more can step up to the Stage 2 Assembler Special or browse the full range of lower kits to match their project.
