Hi All
I have gone for a halfhitch FTX mount so the M2 will be an extra.
The mount is lightly used,almost like new bought from Optcorp in 2012.
It rides on 3 inch Teflon bearings and has a 3/8 inch threaded mounting bore.Takes Vixen bars in a 3 inch spring loaded saddle.
Price 200 Aud .Pick up preferred as postage may not be economical as the mount weighs 1.9kgs
Any questions welcome
