Ambi safety is ok - RISE Armament Ambidextrous Safety Selector

I had higher expectations for this safety. The 69° throw is not much different than a 90° The stepped ridges are sharp & flipping the safety on/off during quals/shoots may give one a blister on the thumb. This safety caused my trigger to stick a little bit. The poor tolerances means there is a signifcant gap b/t safety & lower receiver. But overall, the safety does its job.
