Dear Diana fans, after reading your interesting and "emotional" topics about springs etc. another question to put your focus on instead of putting your energy in the wrong discussions: is there any experience in Gas Ram conversion of Diana air rifle's ? I have all my goods complete ( unfortunately HW parts ) to start with a Gas Ram conversion on a Diana but I am very curious if one of the very inventive Dianawerks Collective members have already done this. I suppose these conversions must be THE answer for a lot of spring problems. ( Of course I will contact Warren immediately when I am so far that I can shoot the "Diana Gas Ram" !! ) Best regards from Johannis. TRY TO BE FRIENDLY FOR EACH OTHER FOLKS !!
it has been a long time since a civil voice speaks out and do appreciate the support and friendship you provide
sometimes this forum is like the "Wild West" with gun's blazing but when the smoke clears and the dust settles everithing comes back to normal
eventually the Gas Ram system will come to the Dianas but with a limited exposure. the spring community will always stay loyal to the coils inside their air guns but just like the PCPs' the Gas Ram will eventuallu make its introduction, its just a matter of time

I've heard the remarks that there is no torquing or fatigue from staying cocked for a long time. Also seen where the firing cycle was described as harsher than when spring'd. Do they take the same effort to cock?
A ram is rarely the answer. Cocking force will be approximatly the same if you want the same fpe from the gun. Yes, you can keep it cocked longer, but is that really an issue? Most springers can be kept cocked for hunting purposes without suffering any ill effects. Recoil will be similar, but not as destructive due to the nature of a cushion of air vs. a coil spring so a gun may hold a scope better. Aside from that, there isn't much difference. You can't tune a ram either - what you have is what you'll get. You can tune a spring and for most people, a tuned spring beats a ram every time. A ram goes bad - replace it at a high cost. A spring wears out (uncommon) replace it at a m odest cost. I know some will chime in and say that isn't necessarily the case, but I have shot both in the same fpe class side by side and I can say a tuned springer is a better shooting rifle than a gas ram if energy in both is the same.
"but I'll be needin' that gun, fer squirrels and such."
Bill. I 've read the same things and I 'm of the same opinion. I was looking to buy a used Kodiak/Patriot a few months ago so naturally I started researching the gas ram options that are available for these guns as I was thinking of a tune or conversion as soon as I would get one. I posted questions on the yellow forum as well as e-mailed people that had done the conversion. About half the people that had done a ram conversion said they went back to spring or liked spring better, especially if tuned, and the majority of the other half didn't say they wanted to convert back, but said the gun's cocking effort or the recoil had increased, or both. I believe the RAM kits for the Patriot/Kodiak offered about 1ft-lb more power. Several also said that the gas ram normally fails after 3 to 5 years at the most, depending how many pellets you go through, and felt that for the price, it should last a lot longer. Those who had "early failures" went back to spring.
With the exception of the GISS gins, Dianas generally use a center shaft in the piston for trigger latch. This makes the economical manufacture of a gas cylinder problematic. It also increases the number of seals needed and consequently raises the odds of seal failure.
advantages and dis-advantages of the gas ram (GR) versus the spring (S)
GR; just a modified shock absorber with plenty of seals in it to go Bad, consistent without the hard recoil, easy to change if it goes bad, expensive if you have to exchange and you get exactly what it puts out in FPS again and again
S; you can tune and de-tune, last longer than a GR, cheap, easy to change just old fashion
