The spring is very durable and a bit longer than the M90, so it may be difficult to install, but other than that I highly recommend it. It greatly increases the shot power; you just need to make sure the battery voltage is appropriate.

The spring actually delivers an M120 rating, its value is highly exaggerated by the manufacturer. Otherwise, no complaints.

The spring is about 2 cm longer than the 140 one. Not much to say, it works ;)
