M4 Recon 3.0 Viper S (Evolution Airsoft)

Recon 3.0

The Recon 3.0 series is designed to deliver high performance, maximum precision, and absolute reliability. Entirely designed in Italy, the Recon 3.0 caters to the most demanding players who expect the best from their gear in any scenario—from CQB to the most extreme and intense outdoor operations.
New Evolution Cargo Stock™ telescopic stock, designed in Italy by Evolution.
New EMR™ (Evolution Modular Rail) aluminum handguard, completely redesigned and CNC-machined for extreme durability, featuring a Duralite™ finish that enhances scratch and abrasion resistance.
Ergonomic grip with tool-free motor access via the TAG system™ (Tool-less Access Grip).
The new EMR™ handguard and free-floating barrel are securely attached to the upper receiver using a new CNC-machined barrel nut featuring threaded ports. The EMR handguard is fastened to this barrel nut with six steel screws, creating a unified structure with the barrel and upper receiver that offers exceptional rigidity with zero flex.
Attention to detail is evident in every component: precision finishes, internal reinforcements, laser markings, steel tactical sling attachment points, and integrated flip-up sights. The construction is extremely rigid and free of wobble. Even after prolonged use, the Recon 3.0 remains as solid as the day it was new.

VIPER Electronic Trigger™ – designed for those seeking true performance
At the heart of the Recon 3.0 platform lies the new ETS IV VIPER™, an electronic trigger system that offers advanced control over firing functions. Unlike other ETU systems, the VIPER is fully integrated into the replica and requires no app or external connection to program its many functions; all settings are adjusted directly via the trigger—simply and intuitively—even during a game.
The VIPER™ utilizes a hybrid electronic architecture combining optical and magnetic sensors to deliver the best of both technologies.

Professional-grade internal components for consistent performance
Internally, Recon 3.0 rifles feature a reinforced aluminum gearbox with 8mm steel ball bearings, PM steel gears with a sector chip (delayer) to support a high ROF, a high-speed piston with full steel teeth, and a spring guide with a forged steel core and bearings. The rotary hop-up system allows for fine-tuning while ensuring consistency and precision—shot after shot—regardless of BB weight.
Tool-free, quick access to the motor compartment and the ability to remove the spring guide without disassembling the gearbox offer great flexibility for future upgrades and customization. The factory-installed ETU is already compatible with brushless motors. The 6.01mm precision inner barrel, featuring a chamfered muzzle end, ensures a flat, accurate shot trajectory. Ample space for high-capacity batteries
The new Italian-designed, ergonomic Evolution Cargo Stock™ was engineered to be the most versatile and user-friendly stock on the market. Dual side compartments triple the available battery space. The rotating butt plate allows for battery changes without ever detaching the plate, simplifying handling.
Despite this spacious design, the stock remains compact and wobble-free.
Lithium batteries (LiPo, Li-ion) can be highly dangerous in the event of a short circuit or damaged wiring—risks that most users tend to underestimate. The new Evolution Cargo stock features a safety system that automatically lifts the butt plate slightly if the wires are not positioned correctly, preventing them from being crushed.

A no-compromise magazine
The Recon 3.0 comes standard with the 140-round Matrixx™ linear-feed magazine, widely regarded as the best currently available. Its dot-matrix texture allows for full customization while ensuring a firm, secure grip, even when wearing gloves. The unique shape of the magazine’s front section—where it meets the magwell—enables ultra-fast extraction, even under pressure.
