I've tested this a fair amount up to semiauto 308 (vid on reddit) but it's still a beta design until many more have as well. Very interested in what other's experiences are.

• Expand on Plaboi's FTN.4 foundation by simplifying assembly, requiring fewer additional retail
  components, and being intended for use with high performing filaments by default
• Reliably withstand 556 and 308 pressures using only plastic
• Incorporate the HUB thread pattern (1.375x24 a.k.a. 1 3/8x24)
  ◦ Increase longevity of attachment point
  ◦ Become compatible with nearly any QD system or other attachment method, and do so
  without the use of commercial flash cans
• Integrate additional performative design features such as baffle clips, flash reducing end-cap
  geometry, etc.

v2 Update: Large improvement added to HUB threads

v3 Update: Small improvement to HUB threads; should be the last update for them.
