Rugged, KVP, and SiCo alpha trilug mounts are trash. They wobble enough for baffle strikes because they use an Oring at the piston insert so it allows the can to tilt due to the squish. So much wobble that the alignment rod would smack against the baffles and end cap.

Griffin is the only one that had the least wobble for Alpha threaded adapters. YHM is the same way for Bravo threaded adapters. Both use a piston insert that does not have an Oring. YHM uses an Oring on its tail cap but that is just for support. Doesn't have as much to do with the spring as you'd think.
Resilient has a titanium Bravo trilug but they said it won't work with wider lugs found on hansohn Brothers and other adapters.
