A replica licensed by STI International

The ASG STI DUTY ONE CO2 GNB features the iconic lines of the famous 1911, modernized by STI International , a renowned Texas manufacturer in the world of sporting and tactical firearms. From the moment you pick it up, you immediately feel its robustness thanks to its full metal construction and exceptionally well-balanced design.

CO2 operation without blowback

This GNB (Gas Non Blow Back) version prioritizes consistency and autonomy. The absence of a moving slide reduces CO2 consumption and improves shot stability. In practice, this results in excellent performance consistency, even during long airsoft shooting sessions.

Full metal construction and tactical ergonomics

The FMV (Full Metal Version) construction provides a realistic feel and excellent overall durability. Weighing in at 820g, this replica maintains a convincing balance without becoming tiring to use. The grip marked with the STI logo and the enlarged beavertail significantly improve comfort and grip stability.

Adjustable hop-up and high power

The adjustable hop-up system optimizes BB trajectory based on the BB weight used. With a power of 1.96 joules and a velocity of 140 m/s, the STI DUTY ONE GNB delivers dynamic performance suitable for target shooting and recreational airsoft .

Integrated tactical rail

The Weaver/Picatinny rail located under the barrel allows for the installation of compatible accessories such as a light or laser. This modularity adds a modern tactical touch while giving the player the ability to customize their setup.

CO2 charger and realistic finish

The removable 16-round magazine incorporates a 12g CO2 cartridge concealed in the grip thanks to the Easy Load system. The STI-engraved slide and unique serial number enhance the realistic and refined appearance of this replica.
