HECKLER KOCH HK45 - METAL SLIDE - GNB - CO2 - BLACK

The HK45 CO2 Non-Blowback replica is a licensed airsoft version of the famous Heckler & Koch pistol, built for reliability, efficiency and recreational use.

The Non-Blowback (NBB) system keeps the slide fixed, without movement during firing, which allows the full direction of CO2 pressure to propel the ball. The result is a constant performance and efficient gas consumption.

Maintenance – Important for CO2 systems

Do not leave the CO2 capsule mounted in the gun or magazine for more than 2–3 hours after use.

Reason:

Constant pressure affects the seals (O-rings).

Gas leaks may occur.

Reduced valve and internal system life.

After use, safely unload the replica and remove the CO2 capsule. For optimal maintenance, periodic use of CO2 capsules with silicone oil is recommended.
