I for one have never understood what everyone sees in the Nikon Bolt for any newer crossbow. The Bolt was made for fixed speed crossbows shooting around 305 FPS with no speed dial to adjust for longer speeds thus making you to have to remember that you are sighted in at 20 yards , 2nd hash is at 33, 3rd is at 46, 4th is at 51, etc. and if you put it on another bow at a different speed it all changes again.
I find it much easier to use a good speed dial scope where my marks all line up at 20-30-40-50, etc.
Maybe it is just me?
