SSR4 Mk1 Gen2, Metal Version

Novritsch SSR4 Mk1 Gen2 – Metal Version AEG Rifle (Black)

The Novritsch SSR4 Mk1 Gen2 Metal Version is a modern and versatile AEG assault rifle based on the AR15/M4 platform, designed to meet the expectations of both beginners and experienced airsoft players. Featuring a full-metal receiver, CNC aluminum M-LOK handguard, and a programmable ETU, the SSR4 Mk1 Gen2 offers a perfect combination of durability, precision, and high rate of fire.

High-End Internals for Maximum Performance

The SSR4 Mk1 Gen2 is powered by a reinforced V2 gearbox (Tokyo Marui standard) with numerous upgraded components:

• CNC 16:1 gears delivering up to 22 BB/s with a recommended 11.1V Li-Po battery
• Full-steel rack piston with CNC piston head
• Stainless cylinder and spring guide with 8 mm ball bearings
• High-torque motor with neodymium magnets
• Rotary hop-up and 6.03 mm precision inner barrel for optimal accuracy

External Build and Design

The rifle features a robust metal receiver with a matte finish and a 14 mm CCW threaded outer barrel. The ergonomic design includes a flat trigger, AR15-style beavertail grip, and ambidextrous controls. The CNC-machined M-LOK handguard allows for accessory mounting (grips, flashlights, PEQ boxes), and the adjustable Crane-style stock fits large buffer-type Li-Po batteries.

Falcon ETU – Programmable Trigger System

The integrated ETU (Electronic Trigger Unit) lets you customize trigger response and firing modes. Key features include:

• Burst and binary firing modes
• Pre-cocking mode
• Trigger sensitivity adjustment
• Battery protection system

Quick Spring Change (QSC) System

The QSC system allows you to change the spring directly through the buffer tube—no need to remove the gearbox, making it easy to adjust your muzzle velocity for indoor or outdoor games.
