Crosman Nitro Piston Conversion

Everything! Much smoother than traditional spring. No twang, just a solid thump.

Nothing

Makes cocking a tiny bit harder, gets easier as you go.

Smooth and makes it quiet.

This is installed in my .22 cal Gamo Whisper. It is smooth, low-recoiling, quiet, and powerful. This sure beats my mechanical-spring air gun.

Not a thing.

Everything this rifle has is awesome and built to shoot. I had it added to my Gamo Whisper and it great.

NOTHING !

ADD this option ! IT is worth the additional cost! seems to make a smoother shooting rifle .

I have both modles of this rifle, with the Venturi and without. I was concerned that I might find I was losing some fps.due to the conversion to the Venturi but there was no decernable reduction. I set up 2 Gamo 5.5x5.5 targets side by side and set both guns on my bench. With open sights I alternated shots, 5 each, from a distance of 50 yds. Neither gun had been fired yet and so weren't sighted. I found the one that was standard a little harder to cock but not painfully so. As I said I sensed no appreciable difference in power and the accuracy of both rifles was about the same for where they were hitting out of the box. Both had a quarter size grouping at the point of impact per gun. I used 8.6 gr. round nosed for both. I truely love these rifles and would be equally happy owning either one if I had to choose.

On both versions I can honestly say that I can't think of one significant thing I'd change.

Other than the fact that the standard version requires a little more effort to cock the only thing of importance and might help you feel better about spending the additional cash for the Venturi is that I believe it will be a better rifle to mount a scope on and have the scope remain true to it's settings.

The Venturi Gas Spring is fantastic. It gives me the feel of a CO2 gun. I well never buy a Steel Spring again.

Give us more conversion options.

Spend the money. The feel is worth every penny.

Quieter, smoother, no spring noise or reverberation. No loss of power.

Nothing, except maybe reduce the price a little.

If your hesitant to make the upgrade to the gas spring, but can afford the upgrade, make the switch...you won't be sorry.
