MAF

MAF (Magnetic Abrasive Finishing) is an advanced surface finishing and polishing technology that uses a magnetic field and fine abrasive particles to smooth surfaces. These particles are controlled by a magnet so they precisely follow the shape of the component and evenly remove microscopic surface irregularities. MAF is therefore a highly precise polishing method that differs significantly from conventional mechanical techniques. Thanks to the magnetically controlled process, it achieves extremely smooth sliding surfaces without altering the geometry. In airsoft pistol trigger mechanisms, it delivers smoother operation, a cleaner break point, and longer service life of parts, making it one of the best technologies for final finishing of functional weapon components.

How does MAF technology work?

During the MAF process, the metal component is exposed to a magnetic field that:

keeps the abrasive particles precisely at the contact area,
ensures uniform pressure across the entire surface,
allows polishing of internal and hard-to-reach shapes.

The result is an extremely smooth surface without sharp edges and without compromising the part’s geometry.

The difference between MAF and conventional polishing

Compared to traditional mechanical polishing (wheels, compounds, manual lapping), MAF offers several key advantages:

MAF: magnetically controlled, constant pressure, micron-level precision.
Conventional polishing: dependent on operator pressure, higher risk of unevenness and edge rounding.

MAF does not remove material aggressively; instead, it micro-smooths the surface, preserving the precise dimensions of functional areas.

Why is MAF ideal for sliding parts of the trigger mechanism?

In airsoft pistols (GBB and GNB), the sliding surfaces of the trigger mechanism have a major impact on trigger feel and operation. These typically include:

hammer contact surfaces,
sear / tooth engagement,
trigger bars,
disconnector contact surfaces.

Using MAF provides:

significant friction reduction,
smoother and shorter trigger pull,
a cleaner break point,
reduced wear of parts.

All of this without the risk of damaging tooth geometry, which is a common issue with improper manual polishing.

Benefits of MAF for airsoft components

consistent surface quality,
preservation of precise tolerances,
longer mechanism service life,
better trigger feel without the need to modify springs.
