Has anyone put an Aluminum Reservoir Extension on their Marauder .22?

How many extra shots did you get? Were you happy with it? Or is it a waste of money.

I personally have not added on this extension, but certainly would. Many have from my travels on various forums. I do have an all aluminum reservoir though on both my Marauders making the overall weight just 5lbs unscoped with synthetic stocks. Whole new airguns after that.

The Marauder reservoir is 215cc. Adding an additional 70cc would be sweet, especially if regulated. I don't think these extensions being aluminum will throw the weight out of balance. I am not sure the all aluminum reservoirs are still available. Someone else may chime in that knows more.
