Hi Parabuteo.

I must start wearing my glasses. I have just checked the card of the mounts I bought and Mike is right, It is TO48 Sportsmatch.

Sorry for giving you the wrong information.

You are right about the Mk1s being accurate. They are my favourite Air Rifle.

I have seven but I think I will soon be selling one and just keeping half a dozen.

All the best.

Dave.
