  Is anyone familiar with Airmagnum.com.ua?
They have some interesting gas ram options, seemingly for everything, and at only $13.49 USD each. Seems too good to be true, but it's awfully tempting to play around with my significant other's Shockwave if they're legit. A 70 Kg gas ram would not go amiss in my learning curve.....

.ua is Ukraine.  Might be a bit unstable.

Yeah, plenty of other options.

  The only other options I was able to find for uprated gas rams was Russian. Might take a few months-if ever-getting it out of customs. LOL

I have some Crosman Shockwaves. Old and new, 177 and 22, all with factory NP gas springs. I like them all.

You are trying to buy an aftermarket gas spring that can store/release more energy?
To increase the Muzzle Energy of the Shockwave above its intended design specifications?

In general that's a bad idea. Tends to over stress the rifle, wear out parts/seals faster, and make it uncomfortable or more difficult to shoot accurately.
Some who try don't like the results and go back to factory NP gas spring.
BUT,  go ahead and try it. You may like the results.

For those folks that HAVE an 18fpe break-barrel and WANT a 30+ fpe break-barrel that shoots well I suggest you BUY a 30+ fpe break-barrel. When you get the new 30+ fpe rifle IN-HAND you will UNDERSTAND WHY the little 18 fpe rifle is rated 18 fpe.

Good Luck! :-)
