Hello all,
I'll start by saying this is my second build AR, and I've done a compensator install on my first AR. But for the life of me I can't remember if I used any kind of adhesive. I sold the first AR a while back. This one has a BCM barrel. I installed an FSC 556 on it and timed it properly an everything, but wondered if I should have use blue loctite, red loctitie, rocksett, etc. It's a 16 inch barrel so I don't want to pin it. Is proper torque enough or do you use thread adhesives? Thanks in advance. BTW I read around, I've read a multitude of different answers.

How did you time it? Did you use a peel washer? Crush washer? By filing? I have never found the need to use any kind of adhesive, especially when using either of the washer methods for timing it.

timed using the provided shims from PWS. I did end up torquing it down pretty hard in order to get it to time correctly. i was stuck between hand tight going past 12 o'clock and pretty damn tight not getting quite to 12 o'clock. I ended up sanding one of the shims down a little to make "pretty damn tight" make 12 o'clock. I don't have a torque wrench, so sorry for the lack of specifics.

Like the others, I don't use any sort of thread locker on muzzle devices.  A crush washer or jam nut do a perfectly adequate job of securing the part.  Instead, I always apply moly grease to the threads.  I like to remove the MDs every so often to clean the accumulated crud off the muzzle crown.  Left unattended, copper removing solvent creeps in and corrodes the crown.  Also, if you tighten your MD on bare threads then shoot hundreds of rounds, you may find the device "carbon welded" to the barrel, making it very difficult to remove. - CW
