Defective couldn't make it work - Badger Ordnance Condition 1 Modular Ambidextrous AR Safety Selector

First off this is solely for an AR. I thought it would work for a ruger precision rifle but the notch on the cylinder is beveled. For an RPR is has to be flat just a heads up. I proceeded to install it on my AR15 since it is a very nice selector switch but come to find out it is out of spec. It's longer than the width of the lower receiver and to top it off it will not cycle through fire mode/safe even though you are supposed to use the supplied detent. I tried using my same detent from my existing selector switch to no avail. No matter how I aligned this selector switch it wouldn't cycle.
