Of rear-handle guns I own an Omer Tempest 70 cm - for five years
durable and precise - had to repair it once.
Most Italian-made gun would be of similar quality and some of them are made in the same factories in Asia where the Italian brands place orders.
But in terms of precision, nothing beats rubber bands unless it is a custom-made pneumat. I find rubber band guns to be more precide and, of course, they are much easier to use and service
