ULTRA LIGHT Piston Head

AirsoftParts ULTRA LIGHT Piston Head – 5.4 g
It is CNC-machined from TECAFORM (POM) engineering plastic and, thanks to its carefully lightened design, weighs only 5.4 g. The front features 9 holes through which air flows beneath the sealing O-ring during compression, expanding it against the cylinder wall and promoting effective sealing. Another 8 holes on the rear significantly reduce weight. The design deliberately omits the 3.8 g axial ball bearing and instead uses a lightweight 1.5 g TECAFORT washer of the same dimensions. The lower moving mass means less energy in the piston assembly on impact and may also affect the dynamics of its movement. The manufacturer therefore recommends this piston head for springs up to M130 and states compatibility with V2, V3 and V7 gearboxes. Made in the Czech Republic.
Key Features

Extremely Low Weight of 5.4 g
The significantly lightened design weighs just 5.4 g, reducing the moving mass of the piston assembly and its mechanical energy on impact.

9 Holes for Pressure-Assisted Sealing
The 9 front holes direct air beneath the O-ring during compression, expanding it against the cylinder wall and helping to properly seal the piston assembly.

CNC-Machined TECAFORM (POM)
The piston head is precision CNC-machined from TECAFORM (POM) engineering plastic, allowing for a lightweight yet functional air seal component.

Lightweight Design Without a Ball Bearing
Instead of a 3.8 g axial bearing, the design uses a 1.5 g TECAFORT washer. An additional 8 lightening holes on the rear further reduce weight.

For Springs up to M130
ULTRA LIGHT is designed for builds with springs up to M130. The manufacturer states compatibility with V2, V3 and V7 gearboxes.
