Stage 2 AR15 Lower Parts Kit With Phosphate-Coated Mil-Spec Internals
This Stage 2 AR15 lower parts kit gives methodical builders a set of mil-spec internals at a competitive price. Every component is phosphate-coated for durability and corrosion resistance, and the kit is proudly made in the USA. It's a practical choice for completing an AR-15 lower receiver build, whether you're assembling your first platform or working through multiple lowers in the shop.
As with any kit, verify compatibility with your specific receiver and intended configuration before assembly. Builders comparing options can review the Stage 3 kit without fire control group or the Stage 5 complete kit to match your trigger preferences and build stage.
Browse the full Lower Kits collection for additional configurations, and keep the correct punches and spring tools on hand. Consider a spare kit for future builds or replacement parts.
