Description

The SA-F05-RL FLEX Gen2 Light Ops HAL ETU, a lightweight and modular AR15/M4-style replica, equipped with a Light Ops stock and a HAL MOSFET

The SA-F05-RL FLEX Gen2 was developed to offer a ready-to-upgrade replica by combining a modern AR15/M4-style platform with reinforced internals and advanced electronic controls. The philosophy behind the FLEX Gen2 line is clearly defined: to enhance players’ experience and the performance of their replicas, resulting in a replica that’s ready to play right out of the box.

Externally, Specna Arms strikes an effective balance between lightness and durability. The body and several structural components are made of nylon-fiber-reinforced polymer, valued for its strength, matte finish, and long-lasting durability. To withstand regular use and handling, certain parts are made of metal to ensure long-lasting durability in the areas subject to the most stress, such as the flash hider, outer barrel, fire selector, magazine release, sights, and cocking lever.

The replica stands out for its Light Ops stock, a minimalist stock designed to reduce weight while maintaining a stable shooting position. It is equipped with non-slip inserts on the cheek rests and a rubber buttpad, which improves stability during rapid fire and transitions. The overall design maintains modern ergonomics thanks to a refined pistol grip and a handguard that allows for the addition of accessories, so you can customize the replica to your playstyle.

Internally, accuracy is ensured by the TDC Magnus™ rotary hop-up chamber (TDC = Top Down Center), designed to provide more precise adjustment. It is complemented by a Helium™ Flat Hop Eraser, intended to improve trajectory stability through more consistent support. The replica also features a high-quality 6.03 mm precision barrel, which ensures a straighter and more consistent trajectory.

All these internal parts are built around the Æther™ gearbox, which features a reinforced chassis designed for reliability. Compatibility with springs up to M140 allows you to upgrade the gearbox to adapt it to the limits and rules of the fields where you play or to suit your playing style. The internals also include 8 mm bearings, steel gears, a polycarbonate piston with metal teeth, and a design engineered to withstand regular use without rapid performance degradation.

The standout feature of this replica is the HAL™ ETU MOSFET, which uses magnetic detection (Hall effect). It allows for full programmability of the SA-F05-RL FLEX Gen2 and delivers excellent trigger response. With this MOSFET, you’ll find features such as active brake, binary mode, trigger sensitivity adjustable across 5 levels, pre-cocking adjustable across 6 levels, as well as programmable firing modes in AUTO and SEMI. Programming via the trigger allows you to quickly adjust performance without needing additional equipment, and the low-battery alarm ensures safe use of the replica. The SA-F05-RL also features the ESA™ quick-spring-change system, which allows you to efficiently adjust the power to suit the demands of the terrain or your playing style.

The SA-F05-RL Gen2 FLEX Light Ops HAL ETU is thus a lightweight, modular, performance-oriented AR15/M4-style replica, featuring a reinforced internal assembly, an ergonomic Light Ops stock, and a HAL MOSFET ready for use right out of the box.

Important Information Regarding the SA-F05-RL FLEX Gen2 Light Ops HAL ETU

The first time you use it, after connecting the battery to your replica, you will hear the HAL ETU™ system’s beep.

After hearing it, hold the trigger in SAFE mode for about 5 to 10 seconds to activate the module and begin using your replica.
