8mm Open Bearing Steel Bushings Specially Manufactured to Withstand Extreme Stresses (B8CA+)

8mm open bearing steel bearing bushes specifically manufactured to withstand extreme stress (B8CA+).
The adoption of these bushings reduces the friction due to the rotation of the gears.
This advantage involves both a higher burst speed and a better use of the energy contained in the battery.
The open bearing guarantees greater robustness than the closed one as the spheres that compose it are larger.
Another advantage of these bushings is the lower thickness which does not interfere with selector plates and rifle bodies.
The dimensions are as follows:
- External diameter: 8mm
- Inner hole: 3mm
- Thickness: 2.5 mm
