Specna Arms AK from the J-Series CORE\u2122 Gen.2<\/h5>\n

The\u00a0Specna Arms\u00a0AKS-74N (SA-J78\u00a0CORE\u2122 HAL ETU Gen.2)<\/strong>\u00a0replica stands out with its\u00a0high-quality external nylon body<\/strong>, which features a\u00a0matte finish<\/strong>\u00a0and\u00a0highly realistic appearance<\/strong>. Reinforced with\u00a0glass fibers<\/strong>, the body is\u00a0very durable and lightweight<\/strong>. Key parts such as the\u00a0outer barrel, gas block, sights, and barrel mounts are made of metal<\/strong>, while\u00a0various small parts and screws<\/strong>\u00a0are even made of\u00a0steel<\/strong>. The rifle has a\u00a0polymer handguard and\u00a0metal folding\u00a0stock<\/strong>. The battery is placed under the dust cover, and\u00a0stick-type batteries<\/strong>\u00a0are recommended.
Right out of the box, the\u00a0AK<\/strong>\u00a0comes with a\u00a06.03 mm precision inner barrel<\/strong>, which\u00a0improves accuracy and shot grouping<\/strong>. Gen.2 is newly equipped with an adjustable\u00a0Magnus\u2122 TDC hop-up chamber<\/a><\/strong>\u00a0with a quality bucking. The\u00a0ORION\u2122 V3 gearbox<\/a><\/strong>, known for its reliability, is\u00a0reinforced<\/strong>\u00a0and supports springs up to\u00a0M120<\/strong>\u00a0(as stated by manufacturer\u00a0Specna Arms<\/strong>). It features a\u00a0QSC quick spring change system<\/strong>\u00a0(ESA2<\/a><\/strong>), allowing you to install a stronger or weaker spring as needed.\u00a0To replace the spring, it\u00a0is not necessary to dismantle the gearbox<\/strong>\u00a0from the\u00a0rifle body.\u00a0Inside, you’ll find\u00a0premium upgrade components<\/strong>\u00a0such as\u00a016:1 gear set, metal nozzle, and reinforced piston with 14.5 metal teeth<\/strong>. The gun is designed for\u00a0S-MAG magazines<\/strong>\u00a0(magazines from Cyma, JG, or E&L may also fit with minor adjustments).<\/p>\n

HAL ETU\u2122 Unit<\/h5>\n

The cherry on top is the\u00a0HAL ETU\u2122 electronic processor unit<\/strong>, which\u00a0takes the rifle’s performance to a whole new level<\/strong>. The name\u00a0HAL<\/strong>\u00a0comes from the principle of the\u00a0Hall effect<\/strong>, which enables the unit to\u00a0detect trigger sensitivity<\/strong>. The\u00a0HAL ETU\u2122 unit offers the following functions:<\/strong><\/p>\n

    \n
  • Trigger detection based on magnetic sensors and the Hall effect.<\/li>\n
  • Active brake.<\/li>\n
  • Binary trigger (fires on trigger pull and release).<\/li>\n
  • Adjustable trigger sensitivity (5 levels from 20 to 100%).<\/li>\n
  • Adjustable precocking (6 levels).<\/li>\n
  • Programmable SEMI firing modes (semi, binary, AUG, sniper with delay).<\/li>\n
  • Programmable AUTO firing modes (auto, semi, 3-round burst, 5-round burst).<\/li>\n
  • Easy programming via the trigger.<\/li>\n
  • Battery low voltage alarm.<\/li>\n
  • Ready for use with Li-Po \/ Li-Ion batteries and brushless motors (e.g.\u00a0Specna Arms Dark Matter<\/strong>\u00a0or\u00a0Warhead<\/strong>).<\/li>\n<\/ul>\n

          HAL ETU unit activation before first use<\/h5>\n

          To make the rifle shoot,\u00a0you must activate the HAL ETU unit exactly following this procedure, otherwise the rifle will not respond to the connected battery:<\/strong><\/p>\n

            \n
          1. Set the fire selector to SAFE.<\/strong><\/li>\n
          2. Connect the battery and wait 3 seconds until you hear a beep.<\/strong><\/li>\n
          3. Hold the trigger for 5 seconds until you hear another beep.<\/strong><\/li>\n
          4. The rifle is now ready for use.<\/strong><\/li>\n<\/ol>","protected":false},"excerpt":{"rendered":"
