Maxx Model M4A PRO hop-up chamber<\/strong> ranks among the absolute top on the market and is designed for demanding players. The chamber is machined from a single piece of aircraft-grade aluminium using CNC<\/strong>, ensuring tight tolerances and perfect alignment with both the receiver and gearbox. The rotary dial<\/strong> allows fine hop-up adjustment, while the redesigned TDC pressure arm<\/strong> ensures even pressure on the bucking. The chamber is fully compatible with R-Hop and standard AEG hop-up buckings<\/strong> and supports nozzles in the range of 21.00 to 21.25 mm<\/strong>, with 21.20 mm working best in most builds (always depends on your setup). Thanks to the BB latching system<\/strong>, BBs stay inside the chamber after removing the magazine and can also be manually released. Precise alignment with the gearbox is ensured by a replaceable inlet adapter<\/strong> and brass guide wings, eliminating misalignment and improving barrel stability. As a great upgrade, we also recommend the EPeS tracer unit<\/strong>, which turns the transparent side covers into an illumination unit for tracer BBs.<\/p>\n
