Specna Arms Oblivion 13:1 Precision Gear Set With Improved Timing

The Specna Arms Oblivion 13:1 Precision Gear Set with Improved Timing has been developed for airsoft players and technicians who want to get the most out of their AEGs. Thanks to the fast 13:1 gear ratio, the innovative Improved Timing and the durable 40Cr steel construction, this gear set is ideal for high-performance builds where a fast trigger response and high rate of fire are key.

The Oblivion series is one of Specna Arms’ most advanced gear sets and meets the requirements of both avid players and professional airsoft technicians.

Improved Timing for maximum reliability

A key feature of the Oblivion Gear Sets is Improved Timing.

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

This offers several advantages:

• Improved BB supply.
• Reduced risk of PME (Premature Engagement).
• Reliable operation at high rates of fire.
• Optimised for powerful high-torque and brushless motors.

For high-speed builds, this contributes significantly to the gearbox’s stable operation.

Fast 13:1 gear ratio

With a 13:1 gear ratio, this gearset delivers significantly higher speeds than standard 18:1 or 16:1 gears.

This means you’ll benefit from:

• Extremely fast trigger response.
• Higher rate of fire.
• Faster cycle times.
• A more immediate response when shooting in semi-automatic mode.

This ratio is particularly popular amongst players who want to optimise their replica for fast semi-automatic performance or high rates of fire.

Made from high-quality 40Cr steel

The gears are made from durable 40Cr steel, which is known for its excellent mechanical properties.

As a result, the gears are resistant to:

• High tax.
• Heavy use.
• Strong feathers.
• Moderne High Torque-builds.

This results in a long service life and consistent performance.

Optimised hardness

Specna Arms uses carefully selected hardness values to ensure maximum durability.

Rockwell hardness:

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

This combination offers an excellent balance between wear resistance and impact resistance.

Designed for high-performance AEGs

The Oblivion 13:1 Gear Set is designed for replicas that combine speed and reliability.

The set is ideal for:

• High Speed builds.
• High Torque builds.
• Brushless motors.
• Fast semi-automatic configurations.
• Performance tuning.

For optimum performance, it is recommended that the gearset be used in conjunction with a high-quality motor, correct shimming and a well-adjusted gearbox.

Strict quality control

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

This means you’ll benefit from:

• Precise dimensions.
• Consistent quality.
• Comfortable fit.
• Reliable operation.

This makes assembly easier and extends the service life of the entire gearbox.

Part of the Oblivion series

Specna Arms supplies the Oblivion Gear Sets in several configurations:

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

This means that there is a suitable gear ratio available for virtually every AEG build.

Practical insights

A 13:1 gearset is a popular choice for players who want a noticeably faster trigger response without immediately switching to an extremely aggressive DSG build. When combined with a powerful high-torque or brushless motor, this gear ratio delivers excellent performance in both semi-automatic and full-automatic modes.

Thanks to the Improved Timing, reliability remains high even when the gearbox is operating at higher speeds.

Who is the Specna Arms Oblivion 13:1 Precision Gear Set suitable for?

Common mistakes

A common mistake is combining a 13:1 gearset with a motor that lacks sufficient power or a poorly adjusted gearbox. For optimum performance, correct shimming, good lubrication and a suitable motor are essential.

You should also check that the battery, motor and spring used are suitable for the higher cycle rate of a 13:1 configuration.

Frequently Asked Questions

What does ‘Improved Timing’ mean?
‘Improved Timing’ means that the tappet plate is activated later, allowing the nozzle to move more efficiently and significantly reducing the risk of nozzle PME during high-speed builds.

What is the advantage of 13:1 over 18:1?
A 13:1 gearset delivers a significantly faster trigger response and a higher rate of fire than a standard 18:1 configuration.

What material are the gears made of?
The gears are made from high-quality 40Cr steel, which is known for its strength and wear resistance.

Are these gears suitable for brushless motors?
Yes. The Oblivion series has been specially developed for modern brushless motors and powerful high-torque builds.

Is this gearset suitable for tuning?
Absolutely. Thanks to its fast gear ratio, improved timing and high-quality finish, this gearset is an excellent choice for high-performance AEG tuning.

With the Specna Arms Oblivion 13:1 Precision Gear Set with Improved Timing, you’re choosing a high-quality gear set that combines maximum speed, reliability and durability. An ideal upgrade for players who want to get the very most out of their AEG.
