- High-density polymer/CNC alu handguard
- 6.03 Tightbore inner barrel
- HAL¹ ETU Pre-installed - Programmable fire modes
This compact platform is exactly what you need for your close-quarters battles. It is short and lightweight, making it a great asset for those who like to stay nimble during their skirmishes. The Specna Arms SA-C21 CORE™ HAL¹ ETU™ M4/AR-15 AEG has an entry-level price point, with veteran-level potential!
This SA-C21 is rocking Specna's HAL¹ ETU, boasting programmable fire controls and several quality-of-life functions built-in, all for barely more money than the original. 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.
