Power ratings were attained using a 300mm-length 6.03mm-diameter inner barrel with a volume-matched cylinder and no hop-up applied. Choice of parts used will affect the final muzzle velocity

Ultimate Mil-Spec AEG springs are manufactured out of the best steel (SiCr) available for springs. With a minimum loss in power and consistency, the Mil-Spec spring series is the ULTIMATE choice for your AEG.

The springs are designed from the start to deliver the best output while keeping it's coil strength, consistancy, and quality. With the closed and ground ends, the spring remains in place during use to prevent a reduction in ROF due to bending.

"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.
