Didn't even touch the threads with the grinder. Cleaned up great.

My question:

I have a .157 washer which puts the bayo lug at 12 O'clock and .161 washer which puts the bayo lug at 9 O'clock, hand tight. If I remove the washer completely, the lug is 15 deg short of BDC.

Can I install the flash hider without a washer?
you can, it's not going to hurt anything, but I suspect you are reaching the bottom of the threads on the barrel and not the muzzle face.
