The HAL¹ allows 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. Like the original, the HAL¹ equipped version also has a 6.03mm tightbore inner barrel, giving it above-average accuracy potential and a slight rise in FPS from the same strength spring.
