Complete motor comes with: casing with integral thrust ring, puck style bulkhead, isomolded graphite nozzle, stainless steel nozzle washer, two snap rings, four buna-n O-rings (dash #338).

Listed casing lengths are "nominal", meaning tolerance of + or - .25". This is no problem because all casings will always hold more than the advertised propellant length.
