Too hard for application - JMac Customs Crush Washer 1/2-28 Muzzle Device

Crush washer no crush under brutal orcish strength. It not working. To be honest, as I attempted to tighten muzzle device and clock it with good torque, the crush washer would not give. I then put washer on my anvil and walked it with a hammer to test it (since wasn't using it now) and it did slightly crush from impact, however deformed non uniformly. Normally I like steal this hard but not in this application.
