Broke at 180 degrees 03/10/2018
Heard it pop at about 180 degrees into tightening. Applied some grease and even backed the flash hider off once at 90 degrees to let the pressure off it. Seems to be very brittle.
Should have listened to the reviews... 13/09/2018
Itâs a simple crush washer - ONLY if you donât need to time the muzzle device. For example, would be great with an A1 flash hider to snug it down - it will never make it to 30ft/lbs. (had my torque wrench set to 20lbs just in case)
I read Dan H. From Nashville Review and thought he just over tightened it - but I should have listened to him. I installed an A2 flash hider (bottom is solid) and needed to tighten it about 120 degrees beyond hand tight. The washer broke well before that. Iâd estimate it made it less than 90 degrees before it cracked. Sadly not worth the effort to return it for a replacement that isnât going to work either...
