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

The muzzle velocity is the most common value given in airsoft replicas and tells us how fast the ball is flying. The value is given in FPS (Feet per Second) or m/s (meters per second). An alternative indication of the gun's power can be by the force of the ball given in joules (J)

As a usually rule, all dealer and manufacturer values are measured at 0.20g. 

Conversion:

• 1 FPS = 0.3 m/s
• 1 J = 99 m/s
• 1 J = 326.7 FPS
