It is made entirely from one piece of 6061-T6 aluminum alloy with a red anodized finish. This material excels in<strong>high strength<\/strong>, while being lightweight. The weight of the entire chamber is only 29 g. It is not a rebranded product from another manufacturer. The chamber was manufactured on <strong>CNC<\/strong> high-quality machines. A quality chamber is a fundamental requirement for the stability and high performance of the weapon. Only metal chambers guarantee maximum production precision without inaccuracies or burrs.<\/p>\n<hr \/>\n<p>QUALITY AND SMART SOLUTIONS<\/p>\n<p>The advantage of this chamber is the<strong>hop-up adjustment ring<\/strong> with numbers. These indicate the level of hop-up adjustment \u2013 from 1 = minimum to 10 = maximum. The selected level is indicated at the top of the chamber next to the M249 HOP-UP text. The levels are fixed in their position by a flexible ball, which provides a click with each rotation. If you don't like being limited to just ten positions, you can replace the spring ball with a rubber ring provided in the package. This makes the adjustment ring stiffer and prevents unwanted rotation.<\/p>\n<p>A significant improvement over the previous generation is the use of a <strong><\/strong>. Now you can use a conventional or shaped hop-up nub. The adapter pushes the hop-up nub horizontally, not with a perpendicular roller as in the original chamber or competing products.<\/p>\n<p>FEATURES<\/p>\n<ul>\n<li>Precise production on CNC machines (chamber, adjustment ring, and centering ring).<\/li>\n<li>Durable monoblock body with high-quality anodized surface.<\/li>\n<li>Metal adjustment ring with limit position stops.<\/li>\n<li>Shaped adapter for conventional hop-up nub.<\/li>\n<li>Laser-marked numbers for a quick overview of hop-up adjustment.<\/li>\n<li>Secure packaging in EVA foam.<\/li>\n<li>Spare parts available upon request.<\/li>\n<li>The chamber is compatible with machine guns <strong>M249<\/strong> from the following manufacturers <strong>A&amp;K, PJ, Classic Army, Echo1, Matrix<\/strong> (tested on original nozzles).<\/li>\n<\/ul>\n<p>PACKAGE CONTENTS<\/p>\n<ul>\n<li>Chamber with adjustment ring<\/li>\n<li>Brass centering ring for barrel<\/li>\n<li>U-shaped adapter for hop-up nub<\/li>\n<li>Spring and ball (to lock the ring in individual positions)<\/li>\n<li>Rubber ring<\/li>\n<\/ul>\n<p>INSTALLATION NOTES<\/p>\n<ul>\n<li>Weapon performance is fundamentally influenced by the seal of the nozzle on the hop-up bucking. For best results, it is advisable to try different types of hop-up buckings and nozzles.<\/li>\n<li>To easily insert the bucking into the chamber, spray silicone oil on the hop-up bucking or into the chamber.<\/li>\n<li>If silicone oil gets into the barrel, remove it. Otherwise, the hop-up will not work.<\/li>\n<li>The 1.5 mm Allen key to secure the barrel in the chamber is not included.<\/li>\n<li>Apply silicone oil or grease on the surfaces between the chamber and the ring before securing the black adjustment ring. Hop-up adjustment will be smoother.<\/li>\n<\/ul>\n<hr \/>\n<p><strong>\u00a7 Notice: Partial technical solutions of this product are protected by copyright!<\/strong><\/p>","protected":false},"excerpt":{"rendered":"<p>The second generation of AirsoftPro Hop-Up chamber for M249 machine guns.
