AeroTech RMS-75/10240 火箭馬達外殼 — 7510C

The machined threads on this casing are clean enough that the closures spin on without any cross-threading, which matters when you're prepping on a dusty range table. Lighter than I expected for a 75mm case too, so it doesn't drag the whole stack down.

Fits the 75mm N2700W-PS reload kit exactly as described, and the liner slides in without any slop once the closures are torqued down. Shipping was quicker than the estimate too.

Machined threads are butter-smooth, and the casing held up flawlessly on my last two high-power launches. The lack of forward seal disc and closures means you’ll need to supply those separately, but the fit with the reload kit was spot-on. Solid build, zero complaints.
