I have a Benjamin Marauder 25 cal, Gen 2 balance valve, Huma 30 cal regulator with Huma pressure gauge in the end of tube, green laminate stock. Absolutely beautiful gun. It needs a o-ring somewhere has a air leak. I have not fooled with the gun since the pandemic. Shoots lights out just don't have a need for it anymore. Someone looking for an awesome gun that has the time to put in o-ring will have a beautiful gun. No scope or bipod. Asking $750 obo. Thanks for looking.
