Muster is a shopping aid, not an assembly guide. Build only to the reload's printed instructions — always the authority — and confirm every part with the manufacturer before you buy or fly.
What you need to fly it
The simplest build — in its own 38/240 case. Reusable hardware you buy once, plus the single-use reload.
Reusable hardware to own

- 38 mm graphite nozzle
Reusable graphite nozzle — fit the throat size your reload's instructions specify

Single-use reload to buy
Single-use: liner, propellant grains, o-rings, and the delay or smoke element (the nozzle and closures are reusable, not in the reload), and ejection charge

- Sparky (metal-loaded) propellant: many ranges restrict these for fire risk. Check your field's rules before flying.
- Loki's graphite nozzle is reusable and sold by throat number — the correct throat for this reload is in its instructions, and the wrong one can cause a failure.
- A dab of high-temperature o-ring grease is needed on assembly (it comes with most hardware sets).
Cases that fly it
Its own case is the simplest; a longer case flies it too, with the adapter and spacers.
