High-density polymer construction
Gen.2 Edition - Aether gearbox
HAL¹ ETU/MOSFET - Programmable fire modes
 
For those who want a lightweight and affordable platform, no matter your skirmishing experience, the Specna Arms SA-F05-RL FLEX™ Gen.2 HAL¹ ETU™ M4/AR-15 AEG is the perfect rifle for you! The SA-F05-RL follows Specna's FLEX™ build style, constructed predominantly from high-density polymer with an alloy outer barrel, resulting in a lightweight and agile build which won't have your arms burning after a gameday!
 
Inside, the HAL¹ MOSFET/ETU system provides superb functionality for this price. It is ready to go toe to toe with other modern MOSFETs, allowing you to program different fire modes, 5 levels of trigger sensitivity adjustment, 6 levels of adjustable pre-cocking, active braking and a low battery voltage alarm. Like the original FLEX™ AEG series, 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.
 
Specna's FLEX™ Gen.2 pushes the featureset of affordable AEGs up a notch or two, equipped with the Aether™ enhanced gearbox shell and Magnus™ TDC Rotary HOP-up unit from the PRIME™ series. Also on board is the Aether™ CNC aluminium nozzle and Helium™ HOP-up bucking, boosting accuracy and range considerably. To make matters even sweeter, you also have the option of choosing the "BLDC/Brushless motor" version, equipped with a Dark Matter Brushless motor for a positively insane rate of fire. If you need a lightweight but advanced backup, the Specna Arms SA-F05-RL FLEX™ Gen.2 HAL¹ ETU™ M4/AR-15 AEG has both boxes ticked!
