    A pair of 30mm adjustable mounts arrived today with weaver bases. The theory being that I'll mount the scope in the adjustables, to the existing 'over' sloped picatinny rail and adjust the front mount upwards to compensate. That saves money on a new rail at about 75 quid, gives me some extra scope height and hopefully solves the original problem I had.

    Anticipated problems are - crossover! They're those mounts on threaded posts, I've had them before years ago and they're buggers to get centred. One solution I'm gonna try is to adjust the zeroing rings inside the units to the extreme of their adjustment, that should ensure both rings are aligned. It'll take the LOS about a mm off barrel centre though.

    Interestingly, I bought them from a supplier in the USA, ordered on the 21st this month, they arrived today, cost including shipping...........................35 quid! I can't find anything in the UK for under 45 quid plus VAT and postage and suspect I'd still be waiting................

    Although................It may yet turn out to be a false economy. I have all day tomorrow to play and see if I can the thing zeroed and not shifting, and without crossover.

    Shame got a set of those B Square adj mounts in 30mm with more than 5 new sets of adjustable post sets unopened. Worst mounts ever came across, cant even place rifle on bag without serious zero shift measured in inches at 20 yards.

    Sportsmatch now do a superb set of elevation adjustable 30mm picatinny mounts.
    Zero shift is not an issue.

    Last set of B squares I had now reside at the bottom of Lough Neagh, I ensured to cut them in half with a hacksaw just incase anyone unlucky enough to come across them, wouldn't be able to use them.

    Glad you got it sorted Lee, any source of grips ?

    Barry, hope you get zeroed tomorrow, and I'll see you at the club but not this week.

    Jinx, yep just waiting on Norris should hear soon.

    Cheers,
    Lofty.

    LIke Barry, I've kept the oversloped rail as I think it adds a lot of stiffness in the breech area. A pair of Sportsmatch height adjustable mounts with Weaver bases were sourced on here, and the job is a good'un.

    I did get a one piece mount with those four riser posts but frankly it's not up to the job; it flexes too easily. We get some strong winds at Shebbear and I don't want variable scope alignment in a force 6 being another factor to contend with. :D:D
