"Perfect spring to get if you want your stock CZ Evo to be under 350 FPS with a 7.4 Lipo

"These springs are excellent quality . I experienced minimal fps loss after a initial break in. The m95 is getting me a consistent 340-345 fps in 2 guns .

"I bought the ASG M135 spring. This thing works great in my Krytac Mk2 gearbox shell. I am using it in my Krytac SPR DMR build in tandem with an R-Hopped Prommy 6.03, and the Lonex mushroom cylinder set (M4 version). With perfect airseal this spring put my gun right at 450 which is exactly what I wanted.

"For anyone who is curious I use this spring on my Krytac Vector. The stock m120 spring with an 11.1v lipo will likely overspin the gearbox, causing the 2 rd. burst to fire 3 shots, etc. The modest upgrade to a m125 spring will be just a little stiffer and make it work as intended. Fortunately this spring did the trick and I also noticed a nice increase in range. Did not chrono the gun yet, but the performance is visible.

"Good spring but be aware this spring is on the longer side. I have a asg 135 and that spring is shorter.

"too long to fit in a V3 gearbox, at least for me. however it is made of good and solid material. the coloring of the end of the spring also makes it easier to identify as a mechanic, which i am not. i'd rate this at 3.5 stars.
