Specna Arms Oblivion 18:1 gear set with improved timing

Specna Arms Oblivion steel gear sets are made for demanding players and airsoft technicians. This 18:1 set (bevel gear, spur gear and sector gear) is made from 40Cr steel with excellent quality control.

Improved timing: piston engagement starts at the second tooth of the sector gear, which according to the manufacturer helps avoid piston pre-engagement (PME) with high-torque and brushless motors.
