Thanks Robert. I guess that there's no reason that they should all have the same threads and they are protecting their sales by having proprietary fittings but it is a pain in the arse. I'm down in the city soon. Any gun shops that you can recommend?
Thanks both.
If anyone here knows of any makes that might fit a 2014 Burris thread, I'd be glad of the help. My local shop sells Nikon, Redfield, Simmons, Swarovski, Leopold, Weaver, Sightmark, Tasco, and Zeiss so I might find one of them that fits.
