This is Dualiry Arms files and design. Just trying to get to the people to help out while they face some issues. I have full permission from them to do this. I’m charging the same as them. Just trying to help some people out while they keep getting screwed on payment processing. 
Make sure not to over tighten the screws when installing the safety levers back on to avoid stripping the holes. 
This is their description:
“We are proud to announce we have developed a 3 Position Safety Cam that pairs perfectly with the Kriss Vector RATL-R.
Our 3 position Safety Cam provides the added convenience to where you will not have to take apart your factory safety cam to install the provided free safety shim that comes with your RATL-R.
Our 3 Position Safety Cam also produces tactile clicks that everyone seems to love so much. Your provided free safety shim will not click into 3rd position”
