This expert product description was prepared by the ANAREUS.cz expert team. All rights to this unique content are bound to the anareus.cz domain.Specna Arms EDGE™ / CORE™ 18:1 is a complete set of cast steel gears for TM-standard AEG gearboxes. The 18:1 gear ratio represents the standard configuration also used from the factory in Specna Arms CORE™ and EDGE™ airsoft guns. The set includes all 3 gears required for the gear mechanism of an AEG gearbox. It is therefore suitable as a replacement for the original gear set when repairing or servicing the gun. The cast construction is designed for builds with springs up to M120. The sector gear also features a polymer sector gear delayer chip. In addition, the sector gear features holes for inserting magnets, allowing it to be adapted for certain electronic units that detect the position or movement of the gear, such as ARES EFCS and similar ETU systems. The magnet is not included.
