Just sold a really nice mk4 isu and scope. Used it for benchrest and it worked really well.i am using an anschutz 1813 supermatch with prone stock and this suits me better.
I made a mount for a BSA Mk II International and used it with a scope. The two mounts are different diameters to accommodate the barrel taper.
I have since sold the rifle so I would be interested in selling the mount (and maybe the scope) if you are interested.
I might swap for the original (aperture) sights.
If you are intersted, I'll send some photos.
Hi just found this topic, I have just bought a purpose made mount for the BSA Martini Mk5 from the Shooting Shed, google should bring up the site, first class piece of kit and at a very good price.. I will send on a pic of my set up, Sightron S111 10-50x60( Hubble hasnt a look in).
