An AR-15 rifle build kit is a comprehensive set of components for assembling a complete AR-15 rifle, typically chambered in .223/5.56. It usually includes a barrel, upper receiver, hand guard, gas system, bolt carrier group, charging handle, lower parts kit, buffer tube assembly, and stock. The kit works with AR-15 lower receivers and is compatible with standard AR-15 parts, making it ideal for shooters and builders seeking a customizable, reliable rifle for target shooting, hunting, or home defense.
