I have Surefire SFMB556 muzzle brakes on two rifles that I use my SOCOM suppressor on. Both muzzle devices were mounted at proper torque and Rocksett in place.

Well, today during dry fires I noticed the brake on one of the uppers spun free from my mere hand torque during suppressor mounting and dismounting! I was lucky to have caught this now and not during live fire or I would have REALLY been upset with a baffle strike.

Should I just pin these muzzle brakes so this never happens again? I'm very much so leaning toward this option as these uppers have not even seen heavy use.
Again, I guess I should atleast be happy I caught this early and my can isn't destroyed... but still... VERY aggravating as my zeros are down the drain now.
