It&#8217;s made entirely from one piece of 6061-T6 aluminum alloy with a red anodised finish. This material excels in <strong>high strength<\/strong>, yet it&#8217;s lightweight. The weight of the whole chamber is only 29 g. It&#8217;s not a re-branded product of another manufacturer. The chamber was manufactured on top quality <strong>CNC machines<\/strong>. A quality chamber is an important prerequisite for stable and high performance of the weapon. Only the metal chambers provide the highest production accuracy without inaccuracies and burrs.<\/p>\n<hr \/>\n<p>QUALITY AND SMART SOLUTIONS<\/p>\n<p>The advantage of this chamber is the <strong>hop-up adjusting ring<\/strong> with numbers. These show the level of hop-up adjustment &#8211; from 1 = minimal to 10 = maximal. The selected level is indicated at the top of the chamber next to the inscription M249 HOP-UP. The levels are secured in their position by a flexible ball, which provides each turn with a click. If you don&#8217;t like to be limited with only ten positions, you can replace the spring ball with a rubber ring from the package. This causes the adjusting ring become more rigid and prevents it from unwanted turning.<\/p>\n<p>A significant improvement since the previous generation is the use of a <strong>U-shaped adaptor<\/strong>. Now it&#8217;s possible to use a conventional or shaped hop-up nub. The adaptor push the Hop-Up nub horizontally, not with a perpendicular roller as in the original chamber, or in competing products.<\/p>\n<p>CHARACTERISTICS<\/p>\n<ul>\n<li>Precise manufacturing on CNC machines (chamber, adjusting ring and centering ring).<\/li>\n<li>Durable one-piece body with high-quality anodised surface.<\/li>\n<li>Metal adjusting ring with stops in limit positions.<\/li>\n<li>Shaped adapter for conventional Hop-Up nub.<\/li>\n<li>Laser-marked numbers for a quick overview of the hop-up adjustment.<\/li>\n<li>Safe packaging in EVA foam.<\/li>\n<li>Spare parts available on request.<\/li>\n<li>The chamber is compatible with <strong>M249<\/strong> machine guns of the following manufacturers <strong>A&#038;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 adjusting ring<\/li>\n<li>Brass barrel centering ring<\/li>\n<li>U-shaped Hop-Up nub adaptor<\/li>\n<li>Spring and ball (for locking the ring in individual positions)<\/li>\n<li>Rubber ring<\/li>\n<\/ul>\n<p>INSTALLATION NOTICE<\/p>\n<ul>\n<li>The performance of the weapon is fundamentally affected by the sealing of the nozzle on the Hop-Up bucking. For the best results it&#8217;s good to try different kinds of HopUp buckings and nozzles.<\/li>\n<li>For smoothly fit the bucking in the chamber, spray the silicone oil onto the Hop-Up bucking or in the chamber.<\/li>\n<li>If silicone oil gets into the barrel, wipe it off. Otherwise Hop-up will not work.<\/li>\n<li>Allen key 1.5mm for securing the barrel in the chamber isn&#8217;t included.<\/li>\n<li>Apply silicone oil or grease on the surfaces between the chamber and the ring before attaching the black adjusting ring. Hop-up regulation will be smoother.<\/li>\n<\/ul>\n<hr \/>\n<p><strong>\u00a7 Notification: Partial technical solutions of this product are protected with copyright!<\/strong><\/p>","protected":false},"excerpt":{"rendered":"<p>The second generation of AirsoftPro Hop-Up chamber for M249 machine guns.
