Just noticed this thread on serial numbers. It's true the reason we were the only crossbow company without serial numbers was because back in the day when crossbows were just getting popular local governments threatened to require anything with a serial number to be registered. This is no longer the case.
The reason we have implemented serial numbers is it gives us complete traceability and in the case of a known issue with a batch of serial numbers we can contact the owners to look after problems before there is an issue. It does help us keep track of who purchased the product and its history. It also greatly helps us with internal quality control. We have had many owners who have had their crossbows stolen or lost and now with serial numbers they will have a better chance of recovery.
I see lots of "the sky is falling" posts about this is the end of Excalibur's awesome warranty and frankly that's BS.
For some reason there are a bunch out there that love to go after our warranty. I can personally guarantee you this does not change our warranty one iota, it actually helps us to improve our quality and service.
We will always do our best to look after any product issues quickly and fairly as we have for the last 35 years, why would anybody think we would want to offer worse service??
Regarding the Assassin crank rope replacement, its actually not that hard to do but for the first while we want to see what happening to the ropes so we can be aware of any rope issues and want to replace the ropes at the factory. So far problems have been few and the Assassin is doing extraordinarily well. We warrant the ropes for 750 shots which is a lot of shooting, we have tested them past this but 750 is a safe number. Its very evident to when the Assassin crank rope needs to be replaced, if there is any torn strands or excessive wear the rope will need to be changed, when in doubt contact us with a photo of the rope and we can confirm with you.
We do offer a great program for Assassin rope replacement, for $49.99 we will replace the rope, replace the string, do a full inspection of the crossbow and ship it back to you. We know that the Assassin crank rope will need to be changed at some point so wanted to make the service affordable as possible. Remember, the average crossbow shooter will maybe shoot their crossbow 30-40 shots a year. For argument's sake lets say 50 shots a year for easy math, that's 15 years before the Assassin will need its rope changed.
I know, most of you guys here shoot that much a day but that's not typical!
Again, if anybody has any questions or issues please feel free to contact me directly anytime.
