Animations out of sync when using IK Hand Gun socket on default epic skeleton

When I attach items to my skeletal mesh normally using any other socket (for example, the right hand bone), they work find and sync correctly. When I attach them to the IK hand gun bone, however, the animation lag far behind are generally out of alignment. I have read several posts on this subject, some of which suggest things like tick groups being the problem but I have not seen any changes from messing around with these. To do the actual attachment I am just using the attach component to component node as I have done in the past to attach any mesh to my character. Does anyone have suggestions as to what this could be?
