Specna Arms Oblivion 18:1 Precision Gear Set With Improved Timing

The Specna Arms Oblivion 18:1 Precision Gear Set with Improved Timing is a high-quality gear set for AEG gearboxes, developed for players and airsoft technicians who demand maximum reliability and durability. Thanks to its improved timing, high-quality 40Cr steel construction and rigorous quality control, this gear set provides an excellent foundation for both standard and high-performance AEG builds.

The Oblivion series is one of the best gear sets in the Specna Arms range and is designed to work seamlessly with powerful springs, high-torque motors and modern brushless motors.

Improved timing for optimum performance

The biggest advantage of the Oblivion series is the Improved Timing.

In this design, the position at which the tappet plate is actuated has been moved to the height of the second tooth of the sector gear. This results in more efficient timing of the nozzle movement.

The advantages of this are:

• Better nutrition for babies.
• Reduced risk of PME (Premature Engagement).
• Reliable operation at high rates of fire.
• Ideal for powerful engines and high-performance builds.

This improvement offers a noticeable advantage, particularly in replicas fitted with brushless motors or powerful high-torque configurations.

Classic 18:1 gear ratio

This model has an 18:1 gear ratio, the most commonly used gear ratio in AEGs.

With this, you’ll benefit from:

• High reliability.
• Smooth operation.
• A good balance between pulling power and rate of fire.
• Suitable for both standard and advanced builds.

The 18:1 ratio is therefore an excellent choice for players who prioritise durability over an extremely high rate of fire.

Made from hardened 40Cr steel

The gears are made from high-quality 40Cr steel, an alloy known for its excellent strength and wear resistance.

As a result, the gears are resistant to:

• High tax.
• Heavy use.
• Heavy feathers.
• Powerful engines.

This ensures a long service life and consistent performance.

Optimised hardness

Specna Arms uses different hardness levels for the individual gears to further enhance durability.

Rockwell hardness:

• Sector Gear: HRC 42-50.
• Spur Gear: HRC 42-50.
• Bevel Gear: HRC 42-47.
• Gear material: HRC 55–60.

This combination ensures an optimal balance between wear resistance and impact resistance.

Suitable for high-performance builds

The Oblivion Gear Set is designed for modern AEG builds where reliability under heavy load is essential.

The set is ideal for:

• High Torque builds.
• Brushless motors.
• Stronger feathers.
• Tuning projects.
• Extensive use of skirmishes.

This makes this gearset an excellent choice for both experienced players and professional airsoft technicians.

Strict quality control

Every Oblivion Gear Set is manufactured under a comprehensive quality control process.

This means you’ll benefit from:

• Consistent dimensions.
• A perfect fit.
• Smooth transmission.
• Reliable performance.

This reduces the likelihood of assembly problems and helps to ensure a quiet, efficient gearbox.

Part of the Oblivion series

Specna Arms supplies the Oblivion Gear Sets in various gear ratios, including:

• 18:1
• 16:1
• 13:1
• 12:1
• Direct Shift Gear (9:1)
• 19 Teeth (SR25)

As a result, there is a suitable configuration available for virtually every AEG build.

Practical insights

In high-performance AEG builds featuring modern high-torque or brushless motors, standard gears may struggle to maintain the correct nozzle timing. The Improved Timing feature of the Oblivion series significantly reduces this risk and helps ensure a more reliable BB feed during rapid firing cycles.

Combined with the hardened 40Cr steel construction, this makes the 18:1 version particularly suitable for players who want to be able to rely on their gearbox for long periods without any problems.

Who is the Specna Arms Oblivion 18:1 Precision Gear Set suitable for?
