Specna Arms Oblivion 13_1 precision gear set with improved timing
Specna Arms Oblivion Steel Gear Set (High-Performance AEG Sprockets)
The Specna Arms Oblivion steel gear set is engineered for advanced airsoft builds, offering exceptional durability, precision, and reliability. Designed to meet the expectations of both experienced players and professional technicians, these AEG gearbox gears are ideal for high-performance upgrades, including high-speed, high-torque, and DSG configurations.
Constructed from premium 40Cr hardened steel, the Oblivion gears provide outstanding resistance to wear and stress, ensuring long-term performance even under demanding conditions. This makes them a perfect choice for upgrading replicas from our airsoft rifles collection or custom builds using components from Specna Arms.
Optimized Timing & Reliability
The Oblivion gear set features an improved timing design, where the tappet plate engagement point has been moved to the second tooth of the sector gear. This significantly reduces the risk of PME (Premature Engagement), especially in setups using strong springs or brushless motors, ensuring smoother cycling and improved feeding consistency.
Available Gear Ratios
- 18:1 – Standard balanced performance
- 16:1 – Enhanced trigger response
- 13:1 – High-speed configurations
- 12:1 – Ultra-fast builds
- 9:1 (DSG) – Dual Sector Gear setups
- 19 Tooth (SR25) – Dedicated DMR platforms
Premium Materials & Hardness
Each gear is precision-machined and subjected to strict quality control standards to guarantee optimal performance:
- Material: 40Cr hardened steel
- Sector & Spur Gear: HRC 42–50
- Bevel Gear: HRC 42–47
- Gear Axles: HRC 55–60
Key Features
