The Matrix CNC Mechbox is machined from High Grade Aluminum with durability in mind. The fully CNC machined aluminum design allows for high tension springs (M150+). Mix that with 8mm bearings and you have a recipe for success. The CNC gearbox comes anodized in chrome for that slick custom look. This and many more custom parts can be found only at!
CNC Processing takes a solid piece of high quality aluminum to machine carve into the shape instead of casting, which makes them MUCH more durable for the longevity you seek!

    "Very well built but poorly designed.
    The fire-selector gear port was slightly too small for most AK platforms (E&L, LCT, and Cyma). You can dremel the fire-selector gear to make it fit.
    The extrusion which guides the tappet plate is slightly too thick; it could cause trouble if you are using the Siegetek gearset or the LCT gearset.

    The gearbox does not have a quick-change spring system.

    The ball-bearings that come with the gearbox shell are garbage.

    Overall, the gearbox is well manufactured, but its design is outdated.
