AIRSOFT PISTON CYLINDERS

Standard bore size cylinder is super smooth for reduced friction, and structurally more rigid thanks to its ribbed design. Suitable for 251mm-300mm precision barrel.

1. made of nylon and fiber 2. the first teeth is made of metal which is covered by a layer of titanium 3. for Tokyo Marui AEG series 4. suitable for high power springs Check out this independent review on Airsoft Mechanics

Reinforced piston from Prometheus is made of highly tensile plastic, which absorbs more impact and much more immune to wear and tear in highly upgraded configurations.

Metal piston head with reinforced O-ring and single direction air inlets for less cycle resistance. Metal piston also makes the report much louder when you fire your AEG!

The milled brass cylinder head for version 4 gear box keep the nozzle stroking at the exact center of the cylinder.

This is a highly recommended upgrade for AEGs with lengthened barrels since you will need additional volume of air to propel the BB out of the longer barrel - to avoid back-pressure. These bore-up cylinders actually have the same external dimensions as a...
