Specna Arms CORE™ 14 Teeth Piston for AR15

The Specna Arms CORE™ 14-tooth piston for AR15 is an original replacement part for M4, M16 and Specna Arms CORE™ AEG replicas. The piston is made from durable polymer and features a solid steel rack with 14 teeth, making it capable of withstanding intensive use and ensuring a long service life.

As part of the Original Spare Parts range, Specna Arms supplies parts of the same quality as those fitted as standard in their replicas.

Reinforced construction for reliable performance

The piston combines a lightweight polymer body with a full-steel 14-tooth rack. This results in a robust construction that can withstand the forces generated during firing.

The steel rack offers greater wear resistance than standard plastic teeth and helps to ensure the gearbox operates reliably.

Suitable for M4, M16 and CORE™ replicas

This piston is designed for use in M4 and M16 AEG replicas and is also fully compatible with Specna Arms CORE™ models. This makes it suitable as a replacement part for maintenance, repairs or a gearbox upgrade.

Thanks to its original dimensions, the piston fits securely onto compatible gearbox components.

Practical insights

A piston with a full steel gear rack is a popular choice when servicing or overhauling a gearbox. The combination of a lightweight polymer body and steel teeth strikes a good balance between weight, durability and reliability. A reinforced piston offers extra peace of mind, particularly for replicas that are used intensively or fitted with more powerful springs.
