Specna Arms Oblivion 18:1 Gear Set SR25 - Improved Timing

This Specna Arms Oblivion 18:1 gear set is designed for SR25 gearboxes, offering a balanced combination of durability and performance. The 18:1 ratio is well suited for general use as well as upgraded builds where consistent and reliable operation is required.

The gears are made from durable 40Cr steel, with hardness optimized to handle load without excessive wear. The improved timing reduces the risk of PME (Premature Engagement), where the sector gear engages the piston too early before it has fully returned forward. This is especially important in high-speed and high-power setups, improving overall gearbox durability.

Optimized timing also supports proper nozzle operation and improves feeding reliability. The gear set is suitable for both standard builds and more demanding upgrade configurations.
