    A very random question.

    Recently I purchased above said scope. It's a cracker I won't fib and a 53 on my first ever HFT at Bisley is testament to that (the cdt Airwolf doesn't hinder that granted) but I have a query on the add on larger sidewheel.

    The one I brought has Allen key grub screws at the 9, 12 and 3 o'clock. I cannot get it to sit square without it moving and I cannot believe this is right. Surely there should be 4 grub screws at the obvious 4 locations and that there should be an additional grub screw at the 6 o'clock?

    Many thanks in advance for those with more experience of these scopes.

    Hi and welcome.

    Just to clarify - big wheel and your shooting HFT? No need as you shouldn't be touching it while doing HFT. Big side wheels give you space for your range finding marks and a bit of precision but that is for the - FT discipline only.

    A bit confused or am I missing something here!

    Your right

    Your absolutely right and I don't have it fitted for HFT so worry not, I was commenting on the quality of the scope not how I use it.

    For the record the sidewheel isn't fitted for comps but I was more musing over whether the sidewheel isn't correctly machined that's all. I'm also tempted to give ft a bash (ok it's not the most appropiate scope I know) it's more to make range plinking for poi checks easier when I'm testing various poi issues.

    Thanks for the vote of confidence and appreciate the welcome.

    I was slightly surprised and chuffed with my first effort. Personally I blame the kit I have more than any skill.

    Still intrigued about the side wheel add on as to whether it's a norm or I got a duffa. I looked at quality of optic when I got the viper but maybe I made a mistake when I ignored the add ons. Lesson learnt.

    Not that I can see its a fully fitting rubber cog internally and the cogs fit the side wheel. It doesn't sit right from an engineering point of view to have grip screws at only 9, 12 and three to have one missing from the 6 o'clock. If they were at 12, 4 and eight I could understand it but they aren't arranged like that.

    If one owns this scope I'm intrigued if mines an anomaly. If mine isn't to spec the fix is easy. Hence I'm asking if it's normal or not.

    That is incredibly generous of you and I cannot thank you enough for your kind offer.

    I shall attempt to rectify it though the shop I recently purchased it from if it proves to be a manufacturing defect so hopefully I won't need to take you up on your generosity.

    I have 2 of these excellent scopes and from recollection, both of the side wheels have 3 grub screws. Having said that, I have never experienced sidewheel alignment issues on either.
