Big Dragon Steel Tooth Piston (14 Teeth) | FREE Delivery over €50 (ROI)

Pistons are a vital part of the AEG system. Factory standard pistons are usually constructed out of polycarbonate, and since the sector gear (main gear) is metal, the teeth of the piston wear out, and can strip. Replacing the piston with a steel-tooth piston gives greater durability to your rifle, although it won't necessarily improve performance. That's more the realm of the piston head. The piston head has an O-Ring that is responsible for pushing air through the cylinder, and out the air nozzle. You can add a bearing piston head for improved durability, or use a silent piston head (this must be paired with a silent cylinder head) to decrease the amount of noise from each shot. There are a lot of options, and it really comes down to what you're trying to achieve.

Big Dragon are a manufacturer of airsoft parts, also known as BD/BD Custom. As part of their lineup, you will find virtually every internal component you might need, as well as externals such as stocks, grips, silencers, and even bodies/receivers. Big Dragon have also started to delve into the tactical gear realm, producing airsoft specific products, such as masks, concealment equipment, and glasses/goggles.

Originally one of the cloners (collective term for a manufacturer that copies existing properties), they grew to prominence for their affordable copy of the G&P M120 motor, however these days they are standing on their own two feet, with many a happy customer returning to Big Dragon as a source of affordable quality.

Aftermarket piston for most electric airsoft guns (AEG) - manufactured by Big Dragon, this piston has a polymer body with a full steel rack, ensuring maximum durability.

We recommend removing the rack and gluing it in place (apply the glue inside the track where the rack slides in & reinsert the rack) for improved performance.

Polymer body pistons help keep the weight down, ensuring snappy response, and lower resistance on the motor.
