Description
The ARES M140 Spring is a replacement mainspring for airsoft gearboxes, catalogued by ARES under the part number SPRING-13 and listed for the Spring Verson fitment. It comes from the brand’s internal parts line, so it is aimed at technicians, upgrade builders and players who strip and rebuild their own replicas rather than at someone shopping for an external accessory.
The M140 marking is the rating ARES gives this spring within its range; check that marking and the SPRING-13 part number against your intended build before ordering, since the spring already fitted may carry a different designation. A mainspring sits inside the gearbox, so the work normally involves opening the shell, and the spring is not accessible or adjustable once the replica is reassembled.
As with any internal part, correct fitment depends on the specific gearbox and spring guide in your replica.
