The latest addition to the Specna Arms range is the Flex Series, a line of ultra-light airsoft weapons perfect for dynamic CQB game that, thanks to its excellent value for money, has immediately established itself as a lightweight and reliable backup weapon. Like all other series, the Specna Arms FLEX line is equipped with a quick-change spring system. Thanks to the ESA System, there is no need to dismantle the gearbox to replace the spring or to adjust the muzzle velocity. The entire spring replacement operation takes about 45 seconds.
