Just picked it up and want to install my  adapter and can.
Is there a preferred method to remove the OEM muzzle device and tighten on new adapter since a traditional reaction rod can't be used

1. Remove rail and use a set of barrel vise jaws
2. Upper Receiver Action Block that uses the take down pins to secure upper receiver----------Receiver is shorter so Upper Receiver Action Block won't work without major mods
3. Upper Receiver Action Block that uses the take down pins to secure upper receiver and has a block to simulate BCG---------Receiver is shorter so Upper Receiver Action Block won't work without major mods
4. Upper Receiver Action Block that clamps to Receiver Pic Rail
5. Upper Receiver Clamshell Action Block

A few observations so far
Upper Receiver is shorter
Charging handle is shorter and has a roll pin for contact with Bolt
No company makes a reaction rod for this bolt type

I put it mine between my legs and used a flash hider wrench. Zero effort and it spun off.  Don’t over think it. I used a SiCo trilug adapter and a drop or two of rock set and reasonable torque. Works great over 1500 rounds later on my Omega 9k.
