Specna Arms Oblivion 18_1 precision gear set with improved timing

Specna Arms Oblivion Steel Gear Set (AEG Sprockets)

The Specna Arms Oblivion steel gear set represents a premium upgrade solution for demanding airsoft players and professional technicians. Designed for high-performance AEG builds, these gears deliver exceptional durability, optimized timing, and consistent operation even under extreme stress conditions.

Manufactured from hardened 40Cr steel, the Oblivion series ensures outstanding resistance to wear and deformation, making it ideal for high-speed, high-torque, and brushless motor setups. Whether you're building a DMR, speedsoft rifle, or DSG configuration, these gears provide the reliability needed for advanced tuning projects.

Improved Timing & Performance

The standout feature of the Oblivion gears is the enhanced timing design. The tappet plate engagement has been repositioned to the second tooth of the sector gear, significantly reducing the risk of nozzle PME (Premature Engagement) in high-stress builds. This results in smoother cycling, improved feeding, and increased gearbox longevity.

Available Gear Ratios

• 18:1 – Standard balanced performance
• 16:1 – Faster trigger response
• 13:1 – High-speed builds
• 12:1 – Ultra-fast setups
• 9:1 (DSG) – Dual Sector Gear configurations
• 19 Tooth (SR25) – Dedicated DMR platforms
