غطاء خلفي للمحرك AeroTech RMS-24/40 - 910791

Took a bit of force to screw on at first, but once seated, the aluminum threads feel solid and reliable. It's noticeably heavier than the plastic closures I've used before, which gives me more confidence for high-impulse reloads.

Fits perfectly on my 24mm case and the anodized finish feels more durable than I expected. No gas leaks during my last three launches.

The threads are machined cleanly and the aluminum feels solid in my hand. It fits my case perfectly with no wobble, and the o-ring groove is deep enough to hold the seal securely. No issues after three launches so far.
