I was going by the specs of the leopard on Pyramid air . When the Leopard first came out I asked the Utah air guys if the 890 cc would work on my FX M4 and the answer was no . I know my M4 very very well !
Please dont let your ego get in the way, I did not mean to offend you, if I did please accept my appologies.
My point was that you are probably not aware of the DRS tube type air system that FX uses on some of its gone and that is why you may have not realized that its says "total capacity", that it meant the two together (air is in the barrel plus the tube). Either that or you did not pay attention to the spec sheet. I highlighted the relevant parts for you in

The
FX Leopard Sniper Bottle is a bullpup airgun that offers precision, power and adaptability. It features the latest FX innovations that excel on their other platforms, brought together in one compact and high-performance package. A new unique FX Leopard feature is that it now incorporates a 54 cc power plenum inside the butt stock.
To cater for different user preferences, the Leopard comes in a bottle and tube variant. This FX Leopard Sniper bottle variant is best suited for long-range and benchrest shooting. It brings the following to the table:
- An additional 480 cc carbon fibre bottle for increased shot capacity
- A Weaver/Picatinny accessory rail for attachments
- A total of 890 cc’s of pressurised air, reducing the need for frequent refills
FX Leopard features:
- 54 cc Power Plenum – has now been hidden away in the butt stock and functions as the buffer between the regulator and the valve. It contains the amount of regulated compressed air needed to thrust out one projectile.
- AMP MkII regulator – regulates the amount of compressed air that enters the power plenum and can be adjusted externally to match the pressure to the preferred ammunition and achieve higher accuracy.
- Quick Tune System – lets the user further fine-tune airflow through macro- and micro-adjustments to the hammer strength.
- Over-barrel PCP reservoir – this shroud air tank reduces the air rifle’s bulk to improve shooting positions and transport. Its pressurised air capacity amounts to 310 cc’s.
PS: I did look at Pyramid air specs and I dont see anywhere they would have said that it had 890cc bottle on the sniper or any version of the Leopard... But I do see how it could be confusing as they completly omitted the word total and also about the tube. They shouldn't misslead people
Anyway lets get back to my question (the topic) and here is hoping someone pops up that knows the answer.
