AirsoftPro CNC M249 Gen.2 Hop-Up chamber

The second generation CNC HopUp chamber for M249 series replicas by AirsoftPro. It is all made of a single piece of aluminum alloy 6061- T6 with red anodized finish . It is a material with high strength, and is lightweight.

The advantage of this chamber is the hop-up adjusting ring with numbers. These show the level of hop-up adjustment - 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'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.

A significant improvement since the previous generation is the use of a U-shaped adaptor. Now it'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.
