I'm not a rep for these guys but the difference is heat durability. Straps melt and have a tendency to rip at the collar point and fail. most suppressor covers aren't able to cope with high fire rate for any duration as the heat is to great etc. Hope this helps. - Godspeed
How do you recommend I tie the kevlar string around the barrel when using a qd device? I like to take my cans off after shooting to avoid carbon lock. I also have had the covers shoot off several times and am having a hard time keeping them on
