The K9 was developed by the Noveske Shooting Team to address the problem with shooting off, through and around flimsy or otherwise non sturdy barricades. The K9 also is very effective when used in port windows and doorways. When used as a brace or support the "teeth" bite into the barricades or ports positively allowing faster follow up shots. When anchored into a support structure, awkward positions are no longer an issue as the rifle is now solid and the flimsy barricade can now be pushed into position for steadier shots.
