benjamin air rifle 357

It probably needs a seal kit.

An alcohol flush won't hurt it and may fix it. Try putting a couple of tablespoons of rubbing alcohol into the pump and then pump and fire it a few times. Do that until it's clear then oil it with Pellgun oil and see if that worked.

There are repair videos on youtube. Mike Baker probably has the seals you need.

Cheers,
