J-ARMAMENT METAL PISTON HEAD
This is a rear intake type piston head for STD AEG made by J-ARMAMENT with a reputation for accuracy.
Feature of this product
Made of metal(hard aluminum) for excellent durability!
It will absorb the twisting of the spring because it has a bearing.
This is a metal piston head made of hard aluminum with high accuracy. Is has no worries such as weak threads, low diameter(periphery) cutting accuracy, and leaks due to O-ring tolerance when fixing piston heads often found in Chinese.
The edge of the outer periphery of the piston head is also gentle and does not scratch the inside of the cylinder. It can be used for all settings such as high cycle and high-power settings as well as normal settings.
Weight: 12g
*The color may change depending on the lot.

This product can be widely used for conventional AEGs.
Not available for next-generation AEGs or specially shaped pistons.
The role of the Piston head
The piston head is a part that is attached to the piston. It is kept airtight in the cylinder by installing an O-ring.
When the piston moves forward, it is a part of flying BB bullets by compressing and discharging the air in the cylinder.
What is a rear intake type piston head?
When the piston head is viewed from the front, there are 6 or 8 holes along with the outer shell. Such a piston head is called a rear intake type.
Because of this hole, the O-ring bulges outward when the piston moves forward, making the cylinder tighter.
Conversely, when the piston is retracted, air can be sucked not only from the nozzle tip but also from the rear of the cylinder.
Since the genuine Tokyo Marui normal piston does not have this hole, intake is only from the nozzle tip. For this reason, when a bullet is clogged, the nozzle tip is blocked and intake is not possible. This phenomenon causes trouble.
