LEISHY 2 REPR STOPPED INDEXING

do the mag turn freely if you remove the index arm spring?
is the mag plate bend? - check this on glass
is the mag free floating in between the breech? - you should be able to slip a slice of copy paper down to the barrel at the front, and down to the puck at the back
..and the puck should be able to move back after each shot, keep it well oiled with silicone oil

Have you checked out this thread https://www.airgunnation.com/threads/leshiy-2-not-indexing.1085930/

This is something that happens often with relatively new owners. Usually in these situations, the barrel wasn't properly tightened and it's come un-seated, i.e. not spaced properly. I'd loosen the barrel and follow the video on how to get it seated properly, then tighten it up carefully.

call Brian he is sure to get you fixed up

If it isn't the barrel being out of position, the 2nd most likely problem is your pressure has dropped down below 60 bar, i.e. you may need to fill your tank. This is what I experience the most often, especially when target shooting. I lose track of how many shots I've taken.

Yes the mag moves freely and i have a spare brand new mag which i have tried,
not sure what you mean by the puck movement ?, i have tried a new oiled puck, There is defo something binding as when i open the gun the magazine jumps round to the next chamber and you can hear a click which sounds like metal on metal, This is literally a brand new gun with under 100 shots this shouldn’t be happening …..

Click to expand...

the puck, under pressure, moves forward do seal against the mag plate (also squares the mag up against the flat part of the barrel so the pellet is perfect in line with the bore) - and the puck spring back a tiny bit if well oiled (like a brake caliper from a brake disc) when the pressure drops so the mag is free to turn
I have no idea what the metal clicking sound may be..

Most common reason I was told of a magazine indexing failure after working fine for a period of time is the barrel has moved back, even slightly. Undo the screws and push the barrel back into the gun with your thumb, hold it there and retighten the screws in the skip pattern till past hand tight then tighten to 25 inch pounds. Also the metal clicking sound may be your spring for your rotation arm has shifted. this is a very easy fix, you can literally lift it up with the arm and place it back in the correct spot. Also the delrin rotation wheel is not made to last for ever. even some wear you can barely see can cause rotation issues. If you have an extra one replace it. Also check the three screws on the hinge plate. Sometimes they get loose. If this happens the plate shifts and causes issues.
