It seems that these springs do the same thing, however the pdi 170 is a littlre more pricey. Is there a difference in performance or quality betweent these 2 springs? thanks.
pdi 170 vs systema 120?

Performance is similar. The Systema spring normally puts out slightly more fps (5-10) but the PDI springs are slightly shorter, making them easier to install. And suposedly, less harsh on the internal gearbox components. I've tried a couple PDI springs (170 & 190) and didn't like the way they sounded after a couple hundred shots. Could've just been the spings though...but I only use Systema now.

try out the guarder 110, weve had good results with it, same fps as m120 and pdi 170
