Specna Arms MK18 CORE(TM) Gen.2 under Daniel Defence(R) license
The Daniel Defence(R) MK18 (SA‑C19 CORE(TM) HAL ETU(TM) Gen2) is equipped with the HAL ETU(TM) electronic processor unit, which takes the rifle’s performance to a whole new level. With this upgrade, Specna Arms moves from mid‑range into the elite company of brands offering the latest technological features as standard. The name HAL comes from the principle of the Hall effect sensor, which detects trigger sensitivity. It also increases the rate of fire and allows safe use of 7.4 V and 11.1 V Li‑Po batteries. They’ve also installed a fully redesigned reinforced gearbox called ÆTHER, capable of handling AEG springs up to M140. Accuracy is ensured by a 6.03 mm inner barrel fitted with a Helium Flat‑Hop bucking in an upgraded MAGNUS(TM) chamber with TDC pressure system. They’ve also included the QSC ESA quick‑spring change system, which allows you to install stronger or lighter springs at will. No need to remove the gearbox from the receiver—the spring change is done easily via the stock tube.
