Complete motor comes with: casing with spiral thrust ring, puck style bulkhead, isomolded graphite nozzle, stainless steel nozzle washer, two snap rings, four buna-n O-rings (dash #230).
Listed casing lengths are "nominal", meaning tolerance of + or - .125". This is no problem because all casings will always hold more than the advertised propellant length.
