Maple Leaf AEG Spring M100

The Maple Leaf AEG Spring M100 is specially developed for AEG (Electric) airsoft replicas and can serve as an upgrade from the standard spring.

We regularly get the question which spring provides which fps/joule, which is very difficult to estimate because it does not only depend on the spring what this value will be after fitting this spring. The airseal of the cylinder, piston and pistonhead, among others, also play a large part in this.
