Well L96 Hop up bucking compatibility?

[Monty 1,886]

As per title, anyone know what buckings are compatible with Well L96s'?

It's APS-2 type sniper gun and so far I've only seen a Falcon rubber that was made for the snow wolf m24 - which is also APS-2. And somewhere I saw you can buy the Well in itself. Really rare.

Thanks!
