I have a 3-prong Surefire flash suppressor/suppressor mount for SF SOCOM762-RC.
Should I use the factory lock-nut, or remove it and direct mount the flash suppressor (timed with shims) and use Rocksett?

Thanks!

Don't use the nut.

Or index washers, just thread the FH all the way on until it bottoms out against the barrel.

Do not us the nut if you plan on using a supressor with it. Clean threads with acetone and wait till it is completely dry then apply rockset to the threads and torque to 20 ft/lbs. No need to time a FH. There will be a small length of threads exposed below the FH, but this is only cosmetic.

Thanks, everyone. BUT the type-A part of me wants the open port of the FH facing up (possibly minimally decreasing muzzle climb and with a solid "tine" on the bottom minimizing dust kick-up (+ the anal "it looks right").
Should I use the SF washer and shims to do this, or should I ****-can the whole idea?

It depends if you are going to run a can or not. If you are not going to run a can then you will not have to worry about a possible baffel strike, so you could use the factory locking nut to time the FH. I would not use the shims because there really is not much of a shelf on the SCAR barrels. From my experience with my other rifles that have timed FH, there is not any more noticeable dusk kick-up compaired to the untimed FH. It seems purely cosmetic when running a 3 pronged FH. I hope this helps!

Yup it does help, thanks. I am going to follow all the sage advice and just screw it all the way on with Rocksett, no shims and no nut.
