Wanted: WTB: stream light Racker for mossberg and other accessories

Looking for one, maybe you don’t use it, maybe never got installed.  Let me know what you’ve got.   I’ve got the 7 3/4” action bars on mine, would like the racker to accommodate. 
Also any other nicknacks for 500/590/88’s out there, mag tube nut with proper sling swivel, fancy highlighter follower, if there’s such thing as an oversized safety for the trigger guard mounted safety.   And magpul stocks would be interesting 

Thanks!
