I was watching a ML video and the guy had this sweet little adapter that makes every jag a spin jag.
It's called the USA.
Here it is.
Total it is 2" the white spin part is 1 3/8"
Pretty cool





It's real new and not posted on their web site.
I sent the guy an e mail and got one.

It's from Chief's pro clean,the makers of the retriver cleaner.
