AeroTech RMS-54 54mm 후면 마감 (소형 노즐 인서트용) - 54ACCSN

Machined threads are clean and it threads on smoothly every time without binding. Fits the small nozzle inserts perfectly and seals up tight for my 54mm reloads.

The threads machined into this aft closure are crisp and clean, so threading it onto the case felt solid right away. Test fit with a small nozzle insert and it seated flush with zero wobble. For the price, it’s a sturdy piece of hardware that does exactly what it should.

Got a perfect seal on the first try with this aft closure, and the threads engaged smoothly without any binding. Only wish it came with a small nozzle insert included, but I know those are sold separately anyway.
