AR-15 Build Kits and Parts Kits for Builders and Gunsmiths

The Build Kits category gathers component packages for the AR-15 platform, giving builders and shooters a single bundle rather than sourcing parts one at a time. The AR15 Range Repair Kit is geared toward on-hand maintenance and replacement parts, while the AR15 WLA Master Parts Kit offers a broader component package for the platform. Each kit is American-made, mil-spec hardware from White Label Armory.

These kits suit a range of users, from those assembling or maintaining an AR-15 to experienced gunsmiths and firearms manufacturers evaluating white-label sourcing. Pair a kit with our lower kits and receivers to round out a complete build.

If you need additional drivetrain hardware, review the buffer kits as well. Always check each product page to confirm included components and fit for your specific AR-15 build or maintenance needs before purchasing.
