Just picked up a new sight for my CAMX crossbow... a Tjijicon ACOG XB. The supplied sight was ok, but this is awesome. (It should be though as it costs a lot but I did get it at a reduced price). I always gravitate to top shelf stuff even if I have to save up for months to get it. With advancing age, my eyesight has declined. This will remedy that to be sure. Highly recommended if you have the inclination and coin.
