Open Steel Bearings bushings 8 mm for A a K M249 / M60 / MK43

<p>The adoption of these bushings decreases the friction due to the rotation of the gears.</p>
<p>This advantage results in both a higher burst speed, that a better use of the energy contained in the battery.<br />The open bearing ensures higher strength compared to the closed because the ball bearings that compose it are of larger dimensions.<br />Another advantage of these bushings is the minimum thickness that does not interfere with selector plate and body of the rifles.</p>
<p><strong>The dimensions are:</strong></p>
<ul>
<li>outer diameter: 8 mm</li>
<li>inner hole: 3 mm</li>
<li>thickness of the bushing: 3 mm</li>
