Specna Arms SA-F05-RL FLEX Gen.2 - High Speed Brushless Performance in Tactical Foliage Green
Experience the next evolution of the FLEX series - The SA-F05-RL Gen.2 takes the lightweight - high strength polymer construction that Specna is famous for and supercharges it with a factory fitted Brushless motor and the HAL ETU - This 9 inch M LOK variant in Foliage Green offers a unique - muted aesthetic that excels in overgrown UK woodland - providing a platform that is light enough for all day skirmishing but fast enough to outshoot almost anything in its class -
Key Features and Performance
- High Speed Brushless Motor - A massive internal upgrade providing incredible efficiency - cooler running temperatures - and a blistering rate of fire compared to traditional brushed motors -
- HAL Electronic Trigger Unit - A magnetic sensor based ETU that eliminates mechanical wear - offering programmable fire modes including binary trigger - sniper delay - and adjustable sensitivity -
- Reinforced Polymer Receiver - Built from nylon reinforced polymer to keep the weight down without sacrificing structural integrity - perfect for fast paced - aggressive playstyles -
- ESA Quick Spring Change - Adjust your power levels in seconds via the buffer tube - allowing you to swap between indoor and outdoor site limits without opening the gearbox -
- 6.03mm Precision Barrel - Paired with a rotary hop up unit to ensure your BBs stay on target even at the maximum range of a standard woodland skirmish -
The Pro Take
The FLEX Gen.2 with the Brushless motor is a "sleeper" RIF - On the outside - it looks like a standard polymer M4 - but the trigger response and cycle speed are professional grade - The Foliage Green finish is a standout choice for the UK - as it blends more effectively with ferns and pine needles than standard Olive Drab or Tan - For players who find full metal RIFs too heavy for long Sunday games - the SA-F05-RL offers the perfect solution - combining a featherweight body with the high end internals usually reserved for the PRIME or EDGE series -
UK Spec and Site Performance
Like all Specna Arms RIFs supplied for the UK market - the SA-F05-RL is designed to be fully UKARA compliant - It typically ships at approximately 330 FPS using 0.20g BBs - which sits comfortably under the 1.14 Joule limit for most UK sites - The Foliage Green polymer is particularly well suited for the often damp and muddy conditions of British sites like those found in the Forest of Dean or South Wales - as it is easy to clean and won't corrode like cheaper pot metal alternatives - Whether you are sprinting between bunkers at a local CQB site or holding a ridge line in the rain - the HAL ETU ensures your trigger remains responsive and reliable -
Friendly FAQ
What is the benefit of a Brushless motor? - Brushless motors are far more efficient and don't create the friction or heat of standard motors - This means your battery lasts longer - your motor stays cool during heavy semi auto fire - and your trigger response is noticeably faster -
Can I use an 11.1v LiPo with the HAL ETU? - Absolutely - The HAL system is designed to handle 11.1v batteries perfectly - providing the best possible performance from the Brushless motor and allowing for very snappy semi auto follow up shots -
Is the Foliage Green colour a match for Magpul or other brands? - It is very close - Specna's Foliage Green is a greyish green that works perfectly with tactical gear in Ranger Green - Multicam - or classic British DPM - making it very versatile for different loadouts -
How do I program the different fire modes? - Programming is done entirely through trigger pulls and the fire selector - The HAL ETU uses simple vibration and LED signals to let you know which mode you have selected - allowing for quick changes in the safe zone between games -
