But to answer your question, just about anything you put on your string, slows it down. The slower the string, the slower the arrow.
I don't know anything about cross bows so I'm not sure what you think of when you hear "peep sight", but on a compound bow, the peep sight is tied right into the bow string.
My fault ..I misunderstood
But thanks for the answer
