Why Choose This Kit

Building your own rifle allows you to understand every component and tailor the firearm to your specific needs. This kit provides quality components from a trusted manufacturer, eliminating the guesswork of sourcing individual parts. The black nitride barrel offers excellent corrosion resistance and durability, while the M-LOK handguard provides modern mounting flexibility for accessories.

Important Note

You will need to source a lower receiver separately, as federal law requires licensed dealers to handle that component. Once you have your lower receiver, this kit provides everything else needed for assembly.
