From what I understand, they have the same powerplant. I don't have either one, so am not familiar with schematics/pics etc.

Craig I'm not 100% on the teardown being the same but I think their basically the same gun!

$148 is a small price to pay for regulating piston powered airgun freedom. Yes the RX and the 90 are the same power plants with different stocks. If your rifle is brand new, chances are it doesn't/won't need any work done for quite a while. And unless a previous owner over charged the piston and posibly fried the seal, I doubt any replacement parts will be needed. They are easy guns to service but you will need the right tools and lubes,..... Including the pump. Replacment seals can be purchased from ARH. The same seal used on the R1. Only parts you may need to purchase OEM are the piston and 'floating inertia' o-rings. My advice would be to study every Internet link provide above very thoroughly before you did into your rammer. Awesome air rifles!!!!!

Just did the baby power test on the breech seal and power blew away on the L side big time. I have new ones ordered last nite from PA. Thank for all the help everybody. Craig
