This sling eliminates the negative effects caused by cross slings from the primary weapons system and the breachers shot gun sling. Cross slings can choke the wearer and block access to the chest area of the wearers vest. To wear the Single point Breachers Sling simply attach the tubular nylon support strap under and over the back of your tactical vest/body armor and run your arm through the sling just as you would insert your arm into shirt sleeve.
