FN EVOLYS

[3] On 6 May 2021 FN Herstal released a 20 minute promotional video, discussing the new design, including its technical aspects, and revealing its name: the EVOLYS.

[4] In September 2021, the EVOLYS was first displayed to the public at the Defence and Security Equipment International trade show in London,[5] and it began to enter pre-production the same month.

[8] The EVOLYS uses a lateral feed mechanism with the belt at a 45° angle, and it is fully ambidextrous,[9] with all its controls accessible on both its sides, and it can be loaded with one hand.

This prevents accidents and runaways as even if the bolt moves forward, it won't fire unless the hammer is released by a trigger pull.

[12] Previous machine gun designs had to use multiple rails, which were not integral to the receiver, making the attachment and usage of optics more difficult.
