V2 Ergal Double O-ring Cylinder Head for M4/MP5/G3 80 Shore – FPS Softair

FPS Softair second-version (V2) ergal cylinder head for M4, MP5, G3 and related platforms. The two large sealing O-rings adapt to the cylinders on the market, while the red 80 Shore Urepan pad cushions the firing cycle, for a well-sealed air system and less stress on the gearbox.

How it works

The two large O-rings create an airtight seal between head and cylinder and adapt to cylinders with both large and small bores, so they work without air leaks even with cylinders from different brands. The stainless steel central tube offers greater mechanical strength and less friction. The position of the guide holes brings the front pad into contact with the inner wall of the gearbox, so the high-density Urepan cushions the piston impact as much as possible, while the shape of the rear pad channels air towards the outlet and reduces firing-cycle noise. Urepan resists wear, abrasion and high temperatures and tolerates mineral oils, greases and various solvents, so it keeps its properties over time.

In the field

It is the right part for servicing and upgrading the air system of M4, MP5, G3 and related replicas built to the Tokyo Marui standard. The red 80 Shore rubber is the hardest in the range: FPS Softair recommends it for stiffer springs and fast full-auto bursts. It is machined from ergal and made entirely in Italy.
