CNC stainless steel piston cylinder type B - RetroArms

Recommendation:
1. The cylinder head can be a classic one
2. The piston head can be classic, but it is advisable to use thicker EPeS O-rings,

or alternatively the entire EPeS piston head (POM, Dural), which has a thicker O-ring in the package

CNC stainless steel cylinder

The cylinder is manufactured in several variants, marked with letters A - E.
Each designation signifies use for a specific inner barrel length of the guns,
or in the case of variant E for a different type of gearbox.
The table shows the approximate use of the cylinder for the inner barrel length range.

Inner barrel length

• Type A 130 - 239mm
• Type B 240 - 289mm
• Type C 290 - 369mm
• Type D 370 - 650mm
• Type E (Extended by 10mm) 470 - 650mm

Cylinders are intended only for electric airsoft guns.
The cylinder is made of stainless steel 1.4541 (magnetic steel), by precise CNC turning.
The cylinder has a thermochemical treatment, thus a surface hardness of 630HBA and a black surface,
thus also protected against corrosion.
It is advisable to lubricate the cylinder with oil, not grease - it can slow down the piston head during firing.
