"Great spring,buy it if you are looking for a new upgrade spring.
by Thomas S. on 05/13/2013
"Love the spring. It works as intended, and was much better than the stock spring in the P90 I made. I can't say what the rate of fire is due to me not having a chrono, however I will say it increased my FPS, and the stock spring was a compressed M120

"Put this in my ICS M16A3 as an upgrade to the M100 that was stock. This was part of a complete upgrade that included a cylinder, piston, piston head, spring guide, air nozzle and this spring. Together that brought me from 305-310fps to 345-350fps with .25s. I am using a 9.6v 4200mah battery and it shoots the same rps of 16.6 before and after. Just remember the spring is irregular and needs to be installed with the closely coiled side on the spring guide. Definitely an upgrade over stock and the irregular spring reduces the load in the piston at first but still gives you an fps increase. Pair one of these with a full air seal upgrade and you will be very happy.
