8mm steel bearing bushings with open bearing. - The adoption of these bushings reduces the friction due to the rotation of the gears. - This advantage results in both a higher burst speed and 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 reduced thickness which does not interfere with the selector plate and body of the rifles. The dimensions are: - external diameter: 8 mm - internal hole: 3 mm - thickness: 2.5 mm 100% MADE IN ITALY.
