Works great. It barely threads on before making contact with the dovetail bar. I shaved a little plastic off of the tip of the knob so that it threads on further before it makes contact with the bar. Works fantastically.
S&S has awesome prices and customer service. This sight knob is just that, what I will complain about it that, on the original BG dovetail mount, the divots are so close to the mount that it gets tight with only a couple threads engaged. This makes me nervous, I'd like more threads engaged for longevity.
As a dovetail knob, it's great.
Bought this, and a dovetail mount for my sight, mainly because I wanted an easier option to remove my sight when I put it in the hard case. Definitely a must!
Like the ability to have tool less removal of dovetail.
After going to the trouble of having S&S build me a custom MBG site, the MBG Dovetail Knob makes for easy tear down to fit in my storage case and quick transfer to my other bows. The system is simple, repeatable and it just works. Very pleased.
