Evolution Recon 3.0 Viper MK18 Mod.1 AEG (FMS-6004BB) – Precision MK18, Italian Viper Control

The Evolution Recon 3.0 Viper MK18 Mod.1 (FMS-6004BB) is a purpose-built Smart Airsoft Gun from Evolution International. Designed and assembled in Italy, this MK18 Mod.1 variant brings the Recon 3.0 platform’s Viper™ Electronic Trigger Unit to a compact, combat-ready package — ideal for CQB, tactical runs and milsim ops where accuracy, reliability and instant trigger response matter.

Viper™ Electronic Trigger – Instant, Programmable, Safe

At the heart of the FMS-6004BB sits the Viper™ ETU, a hybrid optical + electromagnetic electronic trigger developed in Italy. Program all functions directly via the trigger — no apps or cables required. The Viper provides ultra-fast trigger reactivity, selectable fire modes and layered safety/diagnostics to keep your rifle working under pressure.

• Programmable Fire Modes: Semi, Full Auto, 3/5 Burst, Binary, AUG, Sniper Delay
• Trigger Reactivity & Pre-Cocking: multiple levels for a crisp, real-gun feel
• Active Brake & Overspeed Protection: prevents piston bounce and gearbox damage
• Battery Safety: low/high voltage cut-off and gearbox-failure protection
• Fast in-field programming: change settings during a game without tools

Compact MK18 Handling, Full-Size Reliability

The MK18 Mod.1 layout gives the FMS-6004BB compact handling without sacrificing internal strength. Built around a robust receiver and Evolution’s EMR modular rail (M-LOK compatible), this rifle balances weight, ergonomics and accessory flexibility — perfect for close-quarters operators and teams who demand fast target acquisition and consistent groupings.
