Melted quickly - Ulfhednar Miragecover Silencer

I took my time with this because I didn't want to melt it. I did a few 1R1 drills with resets in between attempts. The cover was smoking after the third set but it didn't feel too warm. By the end of the 5th set, the straps on the top had melted. I know the description says, "We do not recommend the mirage cover for more than 10 shots fired in quick succession!" but the 10 shots that I fired were over a 5-minute time period. I wouldn't consider this quick succession. The only scenario I could see using this cover would be for a bolt gun and even then, you would need to be loading each round individually after observing hits. Not useful for training with a standard AR15 at all.
