Launching two DMS motors this weekend. Both were purchased this year from Apogee.
Is the thrust ring advisory still a concern?

If so, should I be OK with a healthy bead of CA?
They're probably good.
I always check every DMS with a good strong twist on that thrust ring. Then some thin CA. Cheap insurance.
