Got the original YHM28 4 port and it's pretty bada$$... 2 questions though:


  1. Is the crush washer direction important?  (i.e.  ======<=  or ======>=)

  2. What's the best way to torque this thing down?  You have to hold on to the barrel somehow, can I put pressure on the gas block / FSB, does it have to get plugged into the receiver, try to cinch down the barrel clamps in a vice????



Thanks,
Texan
