AeroTech RMS-38 38mm 浮動式前蓋 - 38FFCS

Finally got around to swapping to the floating closure design on my 38mm builds. That retaining ring really locks in place solidly—no more worrying about the forward closure backing out during prep.

The retaining ring fit snugly and held the closure securely during my L3 cert flight. Machined surfaces were clean with no burrs, and it took less than a minute to swap between reloads.

The forward closure threaded on perfectly with the retaining ring, and the fit on my 38mm case was snug without being tight. Finally got my L1 cert flight with this, and it held pressure flawlessly through the whole burn.
