RE: G5 Optix ME 4 pin Sight w/SmartPin HwHD, .019", RH
You can have it for 75.00 TYD. The floating pin is used for 50yds plus. It's a dial on the outside of the sight that automatically adjust the last pin based on your speed. I never got that far so you'll have to play with it to see how it works.
If interested send me a PM or email.
Thanks
