<p>Set of 14 O-rings for pressing the chamber against the gearbox. <br /><strong>O-rings are slid onto the inner barrel instead of a spring</strong> and push the chamber more against the gearbox. This extends the lifespan of the gearbox and, most importantly, improves performance consistency.<br /><strong>The optimal number of rings is such that the body can be closed with a pin, and at the same time, the chamber is firmly pressed against the gearbox.</strong> <br />O-rings <strong>absorb the energy of the gearbox better than a spring</strong>, and the <strong>chamber does not bounce off</strong>, so the performance remains within a <strong>dispersion of less than 1 m/s</strong> in well-tuned assemblies. Installation usually <strong>achieves a slight increase in performance and extends the lifespan of the gearbox.</strong></p>
<p>sizes of O-rings:</p>
<p>12/8 mm</p>
<p>10/6 mm</p>
<p>11/7 mm</p>
<p><strong>Installation is easy and does not require specialized knowledge</strong> (except for basic disassembly of the weapon to access the chamber), and by installing this set, <strong>you will not void the weapon’s warranty.</strong></p>
<p><strong>In the package, you will find 14 O-rings (sufficient for 2-3 chamber pressings depending on the model of the external barrel manufacturer)</strong></p>
