Hey Tom, You really should consider a after market straight shaft for your EXCALIBUR. It re-distributes the weight, so you can hunt longer, and it has an armcup with an arm strap. If you ever use one, you won't go back to the standard shaft. I have a used one-piece Bill Babbs Straight Shaft Assembly for sale. I am about to post it on the classified forum for $55 shipped UPS Insured to lower 48 states. I also have a EXCALIBUR E-Z TOTE Hipmount Assembly for the Older Model Excalibur, but you would have to do some modifications to it, inorder to make it fit your newer model EXCALIBUR. I am selling it for $35.00 shipped insured to lower 48 states. I cannot post any pictures of the items, do not have the technology or skills to do so.
But, if you are interested, or have any questions, feel free to call me anytime, day or up til late nite 2am.E.S.T.(I'm a niteowl). My ph# (302) 354-5661, if I don't answer, leave your ph#, and I'll call you back on my dime. Good luck with whatever you decide, HH
