I just sat down to really clean my Bushmaster Ar15 and just realized the chamber brush has Military 8-36 threads and all my cleaning rods are 8-32. Darn! I just ordered some spare stuff from Bushmaster too (inlcuding a Dewey coated rod)! Now I need to find the adapter and I don't think any shops around here carry them! Maybe I can find something that will work that isn't Dewey.
