The SSR4

The SSR4 was designed to be the first and last weapon you'll ever need. It goes beyond a standard input, offering consistent performance over a long period of time.

It combines everything you will need from the beginning of your airsoft journey to the advanced stages. Available in metal and polymer.

FEATURES

LIGHTWEIGHT OR REALISTIC?

Both rifles feature the same high quality internal construction. The metal version is precision manufactured using aircraft grade aluminum for a real firearm feel.

The polymer version uses state-of-the-art technology, with high-density fiber-reinforced polymer material. It offers a premium feel in the hand while being shock resistant to withstand tougher use in the field.

FIREPOWER

We made sure that every SSR4 user has remarkable firepower. To achieve this, we combined unique high-velocity components with a precision inner barrel and a rotary Hop-Up unit. You can be sure that this rifle will take your airsoft experience to the next level!

PRO TRIGGER UNIT

Generally, a feature reserved for technicians with the skills and money to install aftermarket ETUs is now pre-installed.

Advanced ETU Features:

  • Binary shot: Allows you to fire 2 shots per trigger pull

semi-automatic: one when you pull and one when you let go.

  • 3-Shot Burst: Replaces full auto mode if chosen.
  • Precocking: The spring is pre-compressed on a semi-automatic, achieving faster trigger response.

Full specs:

  • Operating voltage: 6.0V-12.6V
  • Response time: 25ms
  • 1800A pulse current (mosfet)
  • 300A DC (mosfet)
  • 100A active braking current (mosfet)

ACCURACY

We don't think of accuracy as a feature, but even today it's not a given in airsoft, so: the SSR4 is accurate.

Hop-Up rotary chamber is one of the best designs! It allows extremely precise adjustments, maintaining stability even if you shake the gun violently.

The flexibility of the hop-up and the 6.03 precision barrel have been tested and deliver excellent results. We recommend using 0.28g BBs for the best balance between speed for CQB and accuracy in the field.

MODULAR PLATFORM

With the SSR4 you get all the options, allowing for the construction of various accessories. You can keep things simple with a Red Dot and a grip or go full tactical with suppressors, scopes, grips, lasers, various magazines or optics.

QUICK SPRING EXCHANGE

Is your SSR4 too “Hot” for a CQB scope? Need more power for a wooded area? Just quickly change the spring in the field. An Allen key comes with the gun!

Just be sure to disable pre-cocking by firing the last few rounds on full auto before changing the spring.

ERGONOMICS FIRST

We focused on improving ergonomics. In addition to a modern beavertail style pistol grip, we added a stylish handguard. You can add components wherever you want in the slots, without hindering your movements.

NOVRITSCH'S DEV TEAM

Every part of the system has been carefully selected by experienced technicians with decades of experience building custom AEGs. We understand that it's not a single part that will turn your AEG into a beast, but the whole system and how the parts work together, from the battery to the barrel. The SSR4 is tuned for the highest performance with an 11.1V battery, while ensuring long-term reliability.

INNOVATIVE COMPRESSION ASSEMBLY

To ensure optimal airflow, we chose CNC components. The piston is equipped with a CNC-machined ported aluminum head.

The cylinder head is also CNC machined aluminum, with a custom-designed rugged rubber shock-absorbing pad that makes the system quieter, increases the life of the gearbox housing and ensures correct angle of engagement (AoE). The grooves in the rubber pad offer optimal air flow.

SPEED

Most airsoft AEGs today have 18:1 alloy steel gears, which are more economical to produce but brittle and can break easily, especially in the case of a clogged barrel, causing premature jamming. The higher 18:1 gear ratio also provides slower trigger response and rate of fire.

For this reason, to support the high rate of fire that the ETU is designed to withstand, we opted for more expensive 16:1 CNC solid steel gears and a high torque motor with powerful neodymium magnets.

TRICKS FOR LONGEVITY

We wanted the SSR4 to be, above all, more reliable than ever. To achieve this, we used a few tricks.

First, the SSR4 is equipped with a new and improved reinforced Gearbox, which can withstand pressure without a problem. Together with the installed 8 mm hardened steel bearings, which are more durable compared to traditional ones, a long service life is ensured.

In addition, we used steel for high stress and wear parts: steel gears, steel piston rail, steel cylinder and steel spring guide.

T-DEAN & LiPo READY

With ETU, our gun is fully compatible with LiPo batteries. It also has a pre-installed T-Dean battery connector. These connectors have less resistance and more strength.
