I Have seen quite a bit of companies producing them. They look neat but the problem is... I just do not understand how they could be healthy for the suppressor. When the can heats up the last thing you want to do is retain that heat. Will it mitigate heat mirage in a pinch? Sure. Can you dump a mag and still detach the suppressor without an oven mitt? Probably... But I can't imagine prolonged firing could be healthy for a wrapped can. Are they meant for temporary use or what? For instance can I hotdog a magpul D60 with the echo trigger without burning it up and or damaging my suppressor?
