What Is a Type 0 Cylinder?

A Type 0 cylinder is a full-volume compression cylinder, meaning it uses 100% of the air generated during the piston stroke to propel the BB forward.

This configuration works best with:

• 363mm to 550mm inner barrels

• Rifle-length AEG builds

• DMR-style configurations

• Higher FPS setups

• Heavy BB applications

Longer barrels require more air to maintain proper BB acceleration throughout the barrel length. A Type 0 cylinder ensures sufficient air volume to maximize range, consistency, and efficiency in rifle builds.

High-Strength Stainless Steel Construction

Unlike lightweight aluminum cylinders, the Lonex Type 0 cylinder is made from true stainless steel, offering superior durability and resistance to wear.

Steel construction provides:

• Increased structural rigidity

• Long-term resistance to scoring

• Improved durability under strong spring tension

• Greater longevity in high-stress builds

For upgraded rifles running stronger springs or high-torque gear sets, steel ensures the compression system holds up over time.

Internally Polished for Maximum Air Seal

The interior surface of this cylinder is precision polished to minimize friction between the piston head O-ring and the cylinder wall.

Benefits of a polished inner bore include:

• Reduced O-ring wear

• Smoother piston travel

• Improved air seal consistency

• More stable FPS readings

• Greater overall gearbox efficiency

Lower friction not only improves performance but also reduces strain on your motor and battery during cycling.

Treated Hard Coating Finish

Lonex applies a treated surface coating to further enhance durability and reduce internal friction.

This hardened finish:

• Protects against corrosion

• Minimizes surface wear

• Improves compression consistency

• Extends service life

The result is a cylinder designed to withstand prolonged use without sacrificing air efficiency.

Optimized Decompression Design

Even though Type 0 cylinders are full volume, precision manufacturing ensures proper internal tolerances and airflow control. The size and placement of decompression areas are engineered to maximize usable compression without unnecessary blow-off.

For best performance, Lonex recommends pairing this cylinder with a Lonex cylinder head to ensure proper sealing and alignment within your gearbox.

Ribbed Exterior for Heat Dissipation

The ribbed exterior design increases surface area, allowing the cylinder to dissipate heat more efficiently during extended firing sessions.

While semi-auto DMR builds generate less heat than high-RPS CQB setups, maintaining stable internal temperatures improves compression consistency and long-term reliability.

Understanding Cylinder Types

Choosing the correct cylinder type is critical for performance:

• Type 0: Full volume — ideal for 363mm–550mm barrels (Rifle/DMR builds)

• Type 1: Lightly ported — best for 318mm–510mm barrels (Carbine builds)

• Type 2: Mid-ported — best for 280mm–430mm barrels (PDW/CQB builds)

• Type 3: Heavily ported — best for 45mm–229mm barrels (Short CQB/DSG builds)

For long-barrel rifle setups, Type 0 provides the air capacity necessary to maintain optimal velocity and efficiency.

Installation Notes

• Recommended for users with gearbox experience

• When installing, the cylinder ports must face toward the spring guide

• Proper compression pairing (cylinder head, piston head, nozzle) is essential

Professional installation is recommended for those unfamiliar with AEG gearbox disassembly.

Ideal For

• Rifle-length AEG builds

• DMR platforms
