SSR4 Mk1 Gen2 – Automatic Electric Gun (AEG)

The SSR4 is designed to be super-easy to use. This is the only out-of-the-box solution you’ll need. Plug in a battery, load it with BBs and pull the trigger. No advanced teching or maintenance is needed. Just focus on the fun part! Period.

Generally exclusive to techs who have the skills and money to install an aftermarket ETU. Now already preinstalled.

ADVANCED ETU FEATURES

• Binary Trigger: allows you to fire 2 shots per trigger pull on Semi-Auto: one when you pull the trigger, the other when you let go of it.
• 3-Round Burst - replaces Full Auto, if you choose to.
• Precocking: the spring gets pre-compressed on Semi-Auto, resulting in a faster trigger response. 5 levels to choose from.
• Active Braking & Battery Protection
• Full Cycle Control, Low Battery Warning, Shot Fault Warning, Overheat Protection

FULL SPECS:

• Operating voltage: 6.0V-12.6V
• 25ms Response Time
• 1800A Pulsed Current (mostfet)
• 300A Continuous Current (mosfet)
• 100A Active Brake Current (mosfet)

We don’t consider accuracy to be a feature but even today, it’s not a matter of course in airsoft so here we go: the SSR4 is accurate.

A rotary-type Hop-Up chamber is one of the best designs out there! It allows for extremely precise adjustments while staying consistent even if you shake the gun vigorously.

The hop-up bucking and the 6.03 precision barrel have been thoroughly tested and deliver great results. We recommend using 0.28g BBs for best balance between BB speed for CQB and accuracy for woodland.

Is your SSR4 way too ‘hot’ for a CQB field? Do you need more power for a woodland area? Just quickly swap the spring on the go. An Allan key comes with the gun!

Just make sure to disable pre-cocking by shooting the last few rounds on full auto before you change the spring.

We focused on improving ergonomics. Besides a modern-looking beavertail Pistol Grip, we added a slick handguard. You can add attachments wherever you like in the slots while not interfering with your grip.

To ensure optimal airflow, we opted for CNC parts. The piston is equipped with ported CNC machined aluminium head.

The cylinder head is also made of CNC aluminum with a beefy rubber dampening pad with a custom design that makes the system quieter, gives a longer lifetime to the gearbox shell, and correct angle of engagement (AoE). The cuts in the rubber pad give it optimal airflow.

Most airsoft AEGs today come with 18:1 sintered steel gears. While they are cheaper to produce, they are brittle and can break easily, especially in the case of a blocked barrel, which leads to preengagement. The higher 18:1 gear ratio also provides a slower trigger response and rate of fire.

This is why, to support the high fire rate the ETU is built to withstand we opted for the more expensive 16:1 gears that are CNC cut from solid steel as well as a High-Torque motor with super strong neodymium magnets. This ensures smooth and fast action all the way.

Better trigger response and at least double the lifetime is guaranteed with our gear set.

We wanted the SSR4 to be, above all, even more reliable then before. To make it happen, we used a few tricks.

First and foremost, the SSR4 is now equipped with a new and improved Reinforced Gearbox that can take a beating without breaking a sweat and together with the fitted 8 mm hardened steel bushings which are sturdier and more reliable compared to traditional bearings, they ensure a very long lifecycle.

On top of that, we used steel for parts that tend to undergo a good deal of stress and wear. For that reason, you get steel gears, steel piston rack, steel cylinder, and a steel spring guide.

We are living in the 21st century. With the ETU, our gun is fully LiPo battery compatible. It also comes with the T-Dean battery connector preinstalled. They feature less resistance and more durability.

Starting out with airsoft? To make it as easy as possible for you, we created an extensive video academy not only for using the SSR4 but also for starting out airsoft in general. From finding fields, friends, and getting into the hobby to advanced airsoft stuff. Check it out!
