What parts are needed to build an AR-10?
A typical AR-10 build requires an upper receiver assembly, lower receiver, barrel, bolt carrier group, charging handle, handguard, gas system, lower parts kit, buffer assembly, stock, magazine, and compatible optics or accessories. Because AR-10 platforms are not universally standardized, always verify compatibility before selecting components.
