Goldilocks of crush washers
Like the title says; this crush washer "crushes" just right. I've had some in the past that crushed too easily and some that took way too much force to crush. The two that I received crushed perfectly while keeping it within a 20-30ft-lbs range on the muzzle threads. Both washers also had the proper I.D. so they centered on my barrel threads with ease and they also stayed center when I crushed them down to install my flash hiders.
