Seems to me some of the industrial gas rams are rated for really high numbers (like 500k compressions). Why can't Hatsan achieve something like this? I've only had one fail but that was at something like 800 shots.Dennis

It has shot more than 4k rounds already and still shooting great. It still has the OEM piston seal though. It is about time to change it. I trust the Benji XL nitro pistons. The vortex pistons are filled with compressed air like the Theobens and it is bad for O-rings in the compression chamber of the vortex pistons. Nitrogen filled ones are better. Just a thought, perhaps the vortex pistons could be filled with nitrogen instead.

Yes, probably 3 or 4 times. Nitrogen gas is widely use in industrial and food storage applications. It should be available from an industrial gas supplier.How many bar?As you probably know, it compresses less than air and is less temp sensitive too...-Y
What about Russian rams? Robert from the Philippines had installed them for a couple of years usage.Hopefully, he can share to us about his experience.
