قرص الختم الأمامي من الفولاذ المقاوم للصدأ AeroTech RMS-75 75mm - 75FSDSS

The stainless steel finish is spotless and slides into the forward closure without any binding. It’s a relief to have a seal disc that seats perfectly every time, especially when prepping a motor for launch day.

Machined perfectly—screwed into my RMS case without a hitch. Noticed the stainless threading holds tight even after a few firings.

Finally got a chance to use this forward seal disc with my 75mm reloads and it fit perfectly with no leaking. The stainless steel feels really solid compared to the aluminum one I was using before. Makes assembly much more straightforward.
