<h5>EPeS Sniper Air System Upgrade Set for Well L96 and Maruzen APS-2</h5>
<p>Looking for a way to get the <strong>maximum accuracy, range, and shot silence</strong> out of your bolt-action sniper? Want to buy a <strong>ready-to-use, hand-tuned set</strong> built specifically for your rifle? Need an <strong>easy upgrade</strong> that only requires a <strong>drop-in cylinder replacement</strong>? The EPeS <strong>Sniper Air System Upgrade Set</strong> provides a complete assembly of carefully designed and pre-installed parts that <strong>significantly boost performance.</strong> This includes a tight stainless cylinder with sealed head and Sorbopad, CNC spring guide with bearing and POM sleeve, a high-power M150 spring, and a <strong>CNC Variable Mass Piston (VMP)</strong> with both stainless and dural weights. With the ability to quickly fine-tune piston weight, you can achieve <strong>quiet shots, higher energy, and stable groupings with heavier BBs</strong> (<a href=”https://kamaradsvyhodami.cz/en/dictionary/joule-creep” target=”_blank”>Joule creep effect</a>). The spring guide with bearing and anti-vibration sleeve <strong>reduces noise and vibration, while the <a href=”https://kamaradsvyhodami.cz/en/dictionary/sorbopad” target=”_blank”>Sorbopad</a> protects internal parts</strong> and extends lifespan. Each set is <strong>individually tested at EPeS</strong> for sealing, smoothness, and noise, so you receive a <strong>ready-to-use cylinder unit.</strong> Note: adjusting piston weights is not <strong>plug-and-play</strong> – <strong>proper knowledge of bolt-action mechanics</strong> is required.</p>
<h5>Recommended Piston Weight Tuning Process</h5>
<ol>
<li>Choose your target BB weight (e.g., 0.43 g, 0.49 g).</li>
<li>Test weight combinations from lightest to heaviest and note total piston mass.</li>
<li>Fire 3–5 shots per setup, record average Joules, and monitor noise.</li>
<li>Select the setup with the most consistent Joules and acceptable noise.</li>
<li>Verify performance in the field with hop-up ..
