Fellow big bore and magnum shooters rejoice! Never worry about your cover sliding off again even with the heaviest of recoiling calibers. This is to upgrade a previously purchased cover and you would like to add this option. You will have to ship back your old cover to us at: Cole-TAC, 212 Skyline Road, Unity, NH 03773
The Stricta Cord is an option on all of our suppressor covers that can be used to tie off the cover to the back of your suppressor. This normally not needed on most calibers, but is a nice added benefit if you are going to be shooting those big cannons.
