What is the Blow-Back System? 

The Gas Blow-Back system is a cycling receiver mechanism that imitate the functionality of real fire weapons. Thanks to Blow-Back, the shooter has the full feeling of shooting, even if it is an airsoft replica!

You can recognize the Blow-Back system by the way the slide of the gun moves (cycles) as you shoot.

Types of Blow-Back:

1. Full Blow-Back (GBB)

- fully cycling slide

- maximum shooting pleasure

- the most commonly used version

- higher gas consumption

- more maintenance needed (lubrication of moving parts)

2. Partial Blow-Back

- cycles only part of the receiver (usually only the "receiver shell")

- less realistic shooting feel (weaker recoil)

- less frequent mechanism

- less gas consumption

- stiff trigger

3. No Blow-Back (GNB)

- gas pistols without Blow-Back also do not need to be cocked for each shot

- slide does not cycle when fired

- less gas consumption

- less realistic shooting feel (no recoil)

- stiff trigger
