Is there such a thing as a quick release for shockmounts?

Ambient makes a quick release, also there is a spigot type but I'm not sure who makes it. I was looking for one a while back, but could not find it so I went with the Ambient.

K-Tek also makes a system called the K-QC Quick Connect (http://www.bhphotovideo.com/bnh/controller/home?O=sort&A=search&Q=&sortDrop=Price%3A+High+to+Low&bl=&atl=&pn=1&st=search&mnp=0.0&mxp=0.0&sv=k-tek+spud&bhs=t&shs=k-tek+spud&ac=&fi=all&pn=1&ci=0&cmpsrch=&cltp=&clsgr=).
