Evike.com Airsoft AEG Tip:
Always reset your spring by firing one shot in semi-automatic before putting it away.
M120 / 190% or stronger spring upgrade may require reinforcement of other gear box internal parts.
9.6V or Stronger battery may be required to power higher than stock springs.

"Awesome!! I have tested the M120 in my VFC SCAR-L. At first I was getting 380 fps. Then I put in a different nozzle and BAM! 450-460 fps consistently (Tad hot for an m120). Spring seems to be of the highest quality. Wouldn't mind putting these in all my builds....Had to lock my SCAR to semi due to that nozzle upgrade!
"When I put the spring in my new novritsch ssg-24 I reached 600 fps!!! Now I'm trying to find a m190 spring
"absolutely solid spring! Got 470 FPS out of the M130 on my UAR. No problems, fantastic!
