I have the RX1 in 20 cal. I purchased it new 1989-90.
if you don't have a gauge and pump to 'adjust' the gas ram, it should be obtained.
there's not much difference between the 20 and 22 calibers in FPS and FPE.
there's not a big selection of 20 cal pellets. the Sheridan brand were/are very poor performing (at least that's what I found from mine)
that being said: I wouldn't part with mine.
lead, follow, or get out of the way!
