Great in theory, poor in execution - SilencerCo Suppressor Cover 7.6 Inch Gray AC1740

I have this cover on a YHM TI QD .30 cal Suppressor. I tightened this thing down like I was rigging a boat for a sudden storm of biblical proportions. Within about 20 shots on a standard AR with the suppressor on the entire cover had slipped about halfway off. I tried to fix it but all the metal fittings were hotter than a bighorn pissing on a rock in the middle of August. I got plenty of wonderful burns for my efforts. I somehow managed to get the first two straps undone but not the third because I didn't want to play that game anymore. I left the third on and put it back in my rifle case to take home. It somehow managed to still be hot enough (45 minutes after shooting semi-auto) to leave some wonderful smelling melted spots in my rifle case. So other than reducing all the things I didn't need it to, it failed to deliver on every promise it made. When it was in place it fit very nicely and it did look good, so two stars instead of one.
