Specna Arms AK from the J-Series CORE(TM) Gen.2
The Specna Arms AK105 (SA-J79 CORE(TM) HAL ETU Gen.2) replica stands out with its high-quality external nylon body, which features a matte finish and highly realistic appearance. Reinforced with glass fibers, the body is very durable and lightweight. Key parts such as the outer barrel, gas block, sights, and barrel mounts are made of metal, while various small parts and screws are even made of steel. The rifle has a polymer handguard and M4-style retractable stock. The battery is placed under the dust cover, and stick-type batteries are recommended.Right out of the box, the AK comes with a 6.03 mm precision inner barrel, which improves accuracy and shot grouping. Gen.2 is newly equipped with an adjustable Magnus(TM) TDC hop-up chamber with a quality bucking. The ORION(TM) V3 gearbox, known for its reliability, is reinforced and supports springs up to M120 (as stated by manufacturer Specna Arms). It features a QSC quick spring change system (ESA2), allowing you to install a stronger or weaker spring as needed. To replace the spring, it is not necessary to dismantle the gearbox from the rifle body. Inside, you’ll find premium upgrade components such as 16:1 gear set, metal nozzle, and reinforced piston with 14.5 metal teeth. The gun is designed for S-MAG magazines (magazines from Cyma, JG, or E a L may also fit with minor adjustments).
