إغلاق أمامي ملولب مسدود AeroTech RMS-54 54mm - 54FCPT

The threads on this closure are cut cleanly and it screws into my 54mm casing without any cross-threading. Plugged design means one less o-ring to keep track of at the field. Ran three reloads through it so far and the seal has held fine.

Snagged this to keep my 54mm reloads sealed up between launch days, and the threaded end screws in way smoother than the old closure I was using. Threads line up clean on the casing and no blow-by at all on my last J motor. It's a small part but it does exactly what it's supposed to.

Finally got around to swapping the forward closure on my 54mm reload and the threading engaged smoothly right out of the bag, no binding or burrs. Fits the RMS-54 casing perfectly and the plugged design means I don't have to worry about the charge blowing forward.
