We never realised that setting a scope up like that would give you a lot of clicks in the part of the trajectory where it would really count.

Today, I see Field Target people mounting their scopes on riser rails, which mount atop the standard dovetail on the rifle. I assume that these have some droop built in to enable you to be able to mount the scope in the optical centre. If I understand this correctly, the main advantage would be that this enables you to have less clicks in the 40-55 yards part of the trajectory... which would be a distinct advantage.

But trying to find such a setup and knowing whether I found the right one makes me feel a lot like trying to work on 2010 brake levers/gear shifters for racing bikes when all I knew was 1976 Campagnolo non-indexed gear shifters on the down tube... in other words, I'm stupid.

My questions are:
1. what is the correct phrase to look for when looking for such a riser rail? I see 'picatinny rail' mentioned, but does a picatinny rail allow the use of standard 11mm dovetail mounts? Or do I need a different rail... or do I need to dump my mounts and get different ones? It seems to be the latter...

2. are there specific rails for specific rifles? If so, what would I need for an Air Arms 100 or for an EV2?

Thanks for enlightening a stoopit forrinner!

Or you can buy half inch lifter blocks quite cheaply if that is all you need ??? HOLLY
