Im after a clamp like the one in the picture Im testing 25mm and 30mm bore scopes with a variety of lamps and Im getting fed up having to keep swapping clamps
What are these clamps called and where can I get one from??
Re-set windage and elevation to there centers slacken off and re-tighten your mounts and try again if problem still persists then you might have to shim the mounts  use the search facility on here theres plenty of info
Contact your local Firearms Officer get your paper work sorted and post a cheque then visit your local gun shop and try a few for size
Not forgetting you will need a gun cabinet
Get yourself an Opinel then get on to British Blades .com Speak to a guy called Longstrider once hes worked his magic on the blade you will only ever need to strop it. I use mine every day and its still as sharp as the day he sent it to me
