Gun Build Kits
WHAT IS A RIFLE BUILD KIT?
Our Rifle Build Kits are everything you need to build your own AR15, AR10, or AR9 pattern rifles. We offer full customization on every aspect of the build kit, our in-house armorers will build you a truly custom rifle with over 200 possible combinations of offered components. These are the same kits issued to every gunsmithing student that attends Sonoran Desert Institute, and are the perfect introduction into the vast world of building your own AR15. There has never been a more modular small-arms platform, and the best way to learn customization is with high-quality components pre-fitted for you, and guaranteed to last a lifetime.
WHAT OPTIONS DO I HAVE?
- Handguards - Muzzle Devices
- Calibers - Barrel Length
All uppers are assembled in house by a Marine Reservist Armorer, to your exact specifications. All lowers will require milling before completions, and are fully compatible with our premier line of 80% Lower Jigs. We also offer Aero Precision Rifle Kits, which are a complete Aero rifle build around one of our high-quality 80% Lowers. Need some more info on if a build kit is right for you?
