I made a small error in my video. If you turn the muzzle device to timed and not all the way till the torque wrench finally breaks at 20#, then reduce the setting on the wrench to 15#, it clicks on 15#, but not 20#. That is exactly what you want. This YHM crush washer was the only one I found that actually works correctly. I bought 15 more of them.
