AirsoftPro CNC M249 Gen.2 Hop-up Chamber
The second-generation AirsoftPro CNC hop-up chamber for M249 machine guns is designed to deliver the most consistent performance while providing more precise hop-up adjustment. The chamber is machined from a single piece of 6061-T6 aluminum alloy with a red anodized finish and precise CNC machining free from burrs and manufacturing imperfections. Compared to the previous generation, it introduces a U-shaped pressure arm adapter, allowing the use of both standard and shaped hop-up nubs such as the OMEGA Nub with horizontal pressure applied to the bucking. The metal adjustment ring with laser-engraved numbers makes it easy to repeat hop-up settings, while a spring-loaded detent ball securely holds the selected position. Instead of the 10-position detent ball, you can also install the included rubber ring for smooth, stepless adjustment.
Key Features
One-Piece CNC Construction
The 6061-T6 aluminum body provides high strength, low weight, and precise manufacturing tolerances for reliable operation.
Redesigned Pressure System
The U-shaped adapter supports both standard and shaped hop-up nubs, providing more even pressure on the hop-up bucking.
Numbered Adjustment Ring
Laser-engraved markings from 1 to 10 make it easy to reproduce hop-up settings. A spring and detent ball securely hold the selected position.
Stepless Adjustment Option
The included rubber ring can replace the detent ball, providing smooth adjustment while preventing the ring from loosening on its own.
M249 Platform Compatibility
Compatible with M249 machine guns from A&K, PJ, Classic Army, Echo1, and Matrix when used with original nozzles.
