RE Factor Tactical just restocked their Buttstock Tourniquet Holder and added two new color options: Ranger Green and Multicam. These holders attach to your carbine’s buttstock and secure most of the common TQs. The holder has two retention straps are joined by a cross piece that allows the user to quickly clear both straps at the same time in order to access the TQ.
McNett camo form or COFLEX (vet wrap) works well too.
