If you’re an AK kinda guy but want to stay light on your feet, the Specna Arms SA-J73 CORE™ HAL¹ ETU AK-105 AEG is your ideal primary! A revamped version of the original SA-J73, the HAL¹ ETU version keeps the best bits and adds some innovative new parts into the mix, with the HAL¹ programmable MOSFET taking centre stage. The HAL¹ is ready to go toe to toe with other modern MOSFETs, allowing you to select binary trigger, AUG mode, and sniper delay instead of semi-auto and semi-auto lock, 3-round burst or 5-round burst instead of full auto. Also available are 5 levels of trigger sensitivity adjustment, 6 levels of adjustable pre-cocking, active braking, and a low battery voltage alarm. Also added to the updated SA-J73 is a new rotary AK HOP-up unit design, bringing rotary performance to the table to keep pace with ARs! Like the original SA-J73, the HAL¹ equipped version also has a 6.03mm tightbore inner barrel, giving it above-average accuracy potential and a slight raise in FPS from the same strength spring. If you’re an operator on a budget and need an agile AK with advanced internals, the SA-J73 is exactly that. Rock solid despite its polymer build and kitted out on the inside with goodies you’d never expect at this price, you’re in good hands on the field with the Specna Arms SA-J73 CORE™ HAL¹ ETU AK-105 AEG at your side!
