Building your own firearm is the best way to understand the mechanics of your platform. Our AR-15 build kits and 9mm PCC kits are curated to include every high-performance component needed to complete your project with factory-level precision.

By choosing a manufacturer-direct complete gun kit, you ensure that every part—from the bolt carrier group to the lower parts kit—is engineered to work in perfect harmony, eliminating the "tolerance stacking" issues common in piecemeal builds.

Most of our build kits feature our forged 7075-T6 upper receivers and patented U-LOK rails. Because these kits do not include the serialized lower receiver, they typically ship directly to your door with no FFL transfer required, making them the ultimate convenience for the home builder.

Whether you are assembling a BM-9 pistol or a BM-15 rifle, Brigade kits provide a Lifetime Warranty and the peace of mind that comes with professional-grade American engineering.
