8MM FPS BUSHINGS A&K BEARINGS M249 / M60 / MK43 (FPS-B8M60)

8 mm steel bearing bushings with open bearing for A&K MINIMI / M60 / MK43 (B8M60).
The adoption of these bushings decreases 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 a higher sturdiness than the closed one as the balls that compose it are larger in size.
Technical measures:
. external diameter: 8 mm
. internal hole: 3 mm
. bushing thickness: 3 mm
. thickness: 4 x 8 x 1 mm

100% MADE IN ITALY.
