I have an FX Chrony and sometimes I do not want to attach it to the barrel, especially if I am testing a couple different guns. Since it does not come with a tripod screw adapter, I made this little thing. Just took a short length of 1./2" pvc and put a 1/4-20 helicoil in it. Attach it to the Chrony like a barrel and then to a tripod. Works out great.
