This Gemtech rear thread adapter in 578-28 fits the GM-45 and Blackside suppressor line, letting owners configure their can for hosts using the .578x28 thread standard common to .45 ACP pistols. Gemtech was one of the pioneering names in American suppressors, and its modular mounting components are machined to keep everything concentric — critical for avoiding baffle strikes when swapping between hosts. If you run a GM-45 or Blackside and want to move it across your .45 pistols, this is the correct factory part for the job.
