Cayugad....Thanks for the Williams link. I see that T/C uses a Williams peep on the Omega X7, so I thought that they would know if the same peep could be used on the Firestorm. They acted like they did'nt want bothered ....they just told me that there isn't anything that fits the Firestorm.Hopefully Williams will be more helpfull. If possible ,I would rather have a receiver mounted peep (rather than a tang). Thanks
