MKII GNB CO2 Pistol - Silver / Black
ASG MKII GNB CO2 Airsoft Pistol
The ASG MKII GNB CO2 pistol is a modern reinterpretation of the iconic MK1 platform, redesigned to deliver higher durability, consistent performance, and excellent handling. Built with a full metal upper receiver, reinforced internal components, and a metal CO2 magazine, this pistol is an ideal choice as a reliable backup sidearm or a solid training pistol.
Thanks to its CO2-powered, non-blowback (GNB) system, the MKII offers stable performance even in colder conditions, while maximizing gas efficiency. The ergonomic grip made of fiber-reinforced polymer fits comfortably in the hand and ensures secure control during prolonged use.
Reliable Performance & Practical Design
The pistol is equipped with an adjustable hop-up, allowing precise tuning for different BB weights and improved accuracy. A fiber optic front sight enhances target acquisition in low-light environments, making the MKII suitable for indoor ranges and CQB training. A manual safety adds an extra layer of security during transport and handling.
