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.

"Mission accomplished. Installed in First gen Elite Force CQC with Torque motor and Reaps bucking. Chrono at field 350-352fps with .25's... Field limit Yeah!
"Ordered two. M125 and M120. Good quality spring. Installed both into krytac mk2 spr with a 6.03 barrel. 125 shot 455fps with .20g. 120 shot 445fps with .20g. This was even after 1000 rounds to “break them in”. SHS m110 spring shoots 375fps with .20g. So I believe these springs are much stiffer.
Works perfectly as advertised. Nice construction. Super consistent. Installed the M125 into my Krytac MK2 CRB and now it shoots 405 FPS. Out of the box it shot around 415 FPS but settled down to 400-405 FPS. Perfect for my outdoor needs. Can't beat it for the quality and the price.
