Since Muzzyman88's Allegiance thread is no longer getting any love I'll just ask on a new thread.

On new Bowtechs there is a small end cap on the end of the limbs where the cam's axlegoes through the limb.

Are these end caps designed to allow the cam to rub against them with no ill effects?
There is very little to no[/b] room between the cam & limb cap on any of the ~20 some odd Bowtech bows (except the Guardian) at my dealer so obviously this isn't a freak thing.

Not looking to slam, just trying to figure this out.

If this was the intent of the design so be it, just curious if that is the case. And no, the cam is not rubbing the limb itself, just the end cap.

Did the end cap replace the need for a nylon bushing and if so, will it wear out?
