    Product was shipped quickly and appears to be of excellent quality. I cannot write a review on the cover yet , as I have not fired a round with the cover on. I plan on putting it through full use very soon.

    I originally found your suppressor sleeve from Instagram and then looked up where to buy it. The only complaint I have is that a lot off the colors are listed but not all of them are clearly shown. I wanted one that was fde and the options for the colors only showed some of them with pictures. It was hard to know if coyote brown would match my gun. Only half of the colors had pictures. It turned out to be the color I wanted but I almost didn't order it because I couldn't visually see what color. It all worked out in the end but it would have been nice to see a picture of what color coyote brown actually is.

    Good on suppressed bolt gun

    Using the 7.5" on a Saker 762 - fits perfectly. It definitely does help reduce mirage normally produced from the piping hot can that lays underneath.

    Absloutly amazing. Had my doubts about the usefulness of this product, but it is amazing. I could comfterbly hold the HMMS when the suppressor was over 800 degrees. Worth every penny.

    Top notch

    When chosing a HMMS there really wasn't any competition. The griffon is top quality and stands up to the hottest suppressor. Mine has been attached to a surefire which is on a DD mk18 10.3
