FPS Steel Bushings from 8 mm open bearings (B8CA)

Bushings from 8 mm steel bearings with open bearing (B8CA).
The adoption of these bushings reduces the friction due to the rotation of the gears.
This advantage involves both a higher burst speed, that 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:
– outer diameter: 8 mm
– internal hole: 3 mm
– thickness: 2.5 mm
