So you install this in your string below the center serving and it is suppose to eliminate peep twist?

All it is doing is shortening the string slightly which if you are going to put it in a press to install it you can simply take a half twist out or put a half twist in and accomplish the same thing with out the unnecessary speed robbing weight of this thing.

If I am going to add anything in the string to align the peep sight I will add string leeches and eliminate some string noise.
