<h5>Warnings</h5>
<ul>
<li>Springs from some manufacturers are <strong>significantly overpowered</strong> (e.g., an M130 may behave like M140–150), possibly exceeding gearbox durability. <strong>We recommend using only the included Specna Arms springs</strong>. For other brands, <strong>M120-class springs</strong> are recommended to avoid damage.</li>
<li>If installing a spring with <strong>progressive (irregular) winding</strong>, ensure the <strong>tighter coil end is placed on the spring guide</strong> facing outward.</li>
<li><strong>Never store the rifle with the battery connected.</..
