AIRSOFT PISTON CYLINDERS

Prometheus Aero Cylinder Head Ver. 6 for Marui AEG. High quality part designed to replace the stock item.

Laylax Nine Ball Damper Cylinder Head X-Shock for Marui MP7A1

This hard piston is the best candidate to replace the stock piston due to its superior self lubricity and durability. Made of reinforced POM material, steam processing on the surface result a good rust resistance.

This air seal cylinder is coated with a layer of Teflon for smooth action (Teflon has the lowest coefficient of friction of any known solid material). Tapered front section for keeping air-tight. Suitable for Marui MP7A1.

Fits 301 - 400mm inner barrel.

Standard bore size cylinder is super smooth for reduced friction, and structurally more rigid thanks to its ribbed design. Suitable for 110mm-200mm precision barrel.

Standard bore size cylinder is super smooth for reduced friction, and structurally more rigid thanks to its ribbed design. Suitable for 201mm-250mm precision barrel.

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.

Standard bore size cylinder is super smooth for reduced friction, and structurally more rigid thanks to its ribbed design. Suitable for 401mm-450mm precision barrel.

Standard bore size cylinder is super smooth for reduced friction, and structurally more rigid thanks to its ribbed design. Suitable for 451mm-550mm precision barrel.

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 3 gear box (except AUG model) keep the nozzle stroking at the exact center of the cylinder.

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

Systema Tokyo Marui AUG Cylinder Head (Compatible with SIG550 / SIG551 / SIG552)

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...
