The Maxx CNC Aluminum Hopup Chamber M4E delivers precision engineering for Tokyo Marui and VFC-pattern M4/M16 airsoft rifles. Its rotary dial mechanism enables fine-tuned hop adjustments with minimal play, while the precision-machined hop lever ensures repeatable accuracy shot after shot. The included inlet adaptor maintains perfect nozzle alignment, eliminating chamber wobble that compromises groupings. Brass side wings and a Delrin locking C-clip secure the inner barrel without rotational shift. The integrated BB latch prevents magazine removal spillage and can be manually overridden for chamber clearing. Purpose-built for shooters demanding consistent performance and reliability.
