This wrench, with a short (less than 18") piece of pipe/tubing that I had in my metal tote, got the nut off without too much effort. Probably torqued to the 'standard' of about 40 foot pounds. I'll just go to snug and then align the gas tube when putting it back together.I’ve gotten off similar nuts with a spanner like this. Put a pipe over it for more torque.
Now I need to decide if I use the 80% lower that was already part of the build, or use the new Aero M5 lower for it. Might keep the Aero in case I decide to SBR the AR10 pistol setup (after making sure it's 100%).
