As many of you know the dovetails on Mk6 Airsporters (and other mk's I believe) are very shallow and have no arrestor holes.

I have some good quality Sportsmatch mounts - but these don't really grip the rails well as everything is all 'rounded off' if you know what I mean?

I also gather I need to consider reach-back mounts to allow for the Airsporter's trigger block - Sportsmatch do some special mounts - OP12C which are supposed to be for BSA rifles - but these seem aimed at solving the eye relief probs rather than security to rifle.

So other than filing up mounts to get a better fit - is there anything anyone can recommend please....?
