Top Max - Ergal Cylinder Head with Black Pad - Rof 30/40bbs - Spring 115/150

Specific model for reinforced GearBox V2 G&G and GearBox ICS .

Cylinder head made of CNC ERGAL with anti-vibration design, air seal QUAD-RING for the cylinder, elongated spout for perfect air seal and interchangeable rubber PAD with 5 degrees of hardness to adapt to springs and ROF diversified.

The rubber PADs present on all TopMax cylinder heads are interchangeable, and depending on the color they are recommended for different springs and ROFs. The PAD BLACK is pre-mounted on this cylinder head, recommended for ROF from 30 to 40 bb/s and/or springs from 115 to 150 m/s (also tested with DSG configurations). The rubber with which the PAD is made favors the absorption of shocks and vibrations due to the impact of the piston, the thickness of the PAD is designed to guarantee a perfect AOE (angle of engagement) of the piston on the sector gear, and therefore avoid the use of shims under the piston head (also with a saving in weight and striking mass), the diameter of the PAD favors and assists the air seal on the cylinder, finally the innovative shape of the PAD together with the cone created on the body of the head cylinder, optimally conveys the air inside the elongated spout of the cylinder head, ensuring a faster and more precise air flow exit.

The size and position of the housing holes guarantee perfect adhesion of the front stop of the cylinder head, made of rubber, on the GearBox plates. The millings made on the upper part of the cylinder head body reduce and mitigate the vibrations resulting from the impact of the piston and guarantee the drastic reduction/elimination of the risk of breakages in the head of the GearBox plates. The spout of the cylinder head has an external diameter of 4.70mm, has a slight rounding at the tip for free sliding of the pellet pusher and is slightly longer than other products on the market to help the pellet pusher slide as linearly as possible inside of the T-HopUp chamber.

The TopMax cylinder head is compatible with both GearBox V2 (such as M4, MP5, G3, Minimi) and with GearBox V3 (AK and similar).
