I'm a pretty big fan of the Strike Industries - strike switch... its doo doo in comparison to this selector. I love the Radian Raptor charging handle so I figured I'd take a chance on this selector, I'm so glad I did. It's got to be the most comfortable selector I've used to date. Everything about it screams quality. Like most people I usually have issues with the short side digging in to my hand while shooting. Not with selector! While it does still touch your hand it feels smooth and rounded, no sharp edges to dig in. It comes with a new grip detent and spring, using the selector is crisp and easy to manipulate. So... the one thing I love about it is also its biggest potential issue. I love the way the paddles connect to the selector shaft by way of the dovetail slots and a detent, no screws to strip, no need for loctite. The potential issue would be shooting one of the detents across the state when you need to take it off, just wish they would have included 1 if not 2 extra detents for this possible loss.
