The "How to do it" is in the comments. Boy, was I happy with the results.

That is excellent Sir. I'm glad the conversion worked out well for you.

Be sure to put a drop of pellet gun oil or #1 machine on the ram shaft every tin or so and the ram should have a good long cycle life.

$30 for the ram makes me happy - just thinking forward to the day when my Titan fails.

What model Nitro Piston did you decide to put in there for the Whisper? I looked into this for myself, but there are several models of the Nitro Piston, and I would think that not all of them would fit properly.

Also, who did you go with to buy the piston?

Very exciting that you got the conversion to work to your satisfaction, that's great news!

Crosman customer service #800-724-7486, Part # BT9M22-00-5, $26 + $4 shipping(US)
As far as I could tell, this same piston is used across the entire Crosman NP product line, at least the part # is the same for many of their models.
I had no clue if it would work in the Gamo, but for $30 I'd give it a try.
I have a Black Belt in tinkering, and there was some trial & error fitting, cutting off less than required, until I figured out how it all was suposed to work. In retrospect, it was a surprisingly uncomplicated job.

Nicely done. Do you think that the same gas spring will fit my .177 Gamo Shadow 1000?
