CNC stainless steel cylinder made of stainless steel 1.4541 (magnetic steel) by precision CNC machining with thermochemical treatment (surface hardness 630HBA).
The cylinder is produced in several variants, which are marked with the letters A - E. Each type is designed for a different length of the inner barrel, or in the case of the E variant for a different type of gearbox. The table shows the indicative use for the range of inner barrel lengths.
The cylinder is designed for airsoft electric guns (AEG) only. It should be lubricated with oil, not vaseline (vaseline can slow down the piston head during firing).
|CYLINDER TYPE||LENGTH OF THE INNER BARREL|
|Type A||130 - 239 mm|
|Type B||240 - 289 mm|
|Type C||290 - 369 mm|
|Type D||370 - 650 mm|
|Type E (extended by 10 mm)||470 - 650 mm|
The RetroArms brand is based on the purely czech company Retro FACTORY s.r.o. Representatives of the company have experience with airsoft since 2001. In the beginning, the company was mainly a trading company, where the main activities were the design and commissioning of components for cooperation and assembly into functional units.
RetroArms does not compete with cheap chinese producers, but relies on the original design and high quality of manufactured parts.
Since 2013, it has a new production hall, CNC machine tools for machining complex components, a parts warehouse and a team of experienced workers and developers.
