STI Duty One CO2 GNB BB Pistol

Description

The STI Duty One CO2 GNB (Gas Non-Blowback) BB pistol is a compact, reliable range plinker based on the STI Duty One frame. CO2-powered and shooting .177 BBs at 390 fps, the non-blowback design prioritizes shot count and consistency over slide action — a practical trade-off for target practice and casual plinking. ASG builds solid CO2 pistols and the Duty One is a reliable example of the format.

• .177 BB CO2 pistol: 390 fps for paper targets, cans, and reactive plinking.
• Gas Non-Blowback (GNB) action: Fixed slide maximizes CO2 efficiency for more shots per cartridge.
• STI Duty One replica: Based on the classic STI competition pistol profile.
• ASG quality: Built by a manufacturer with a strong track record in CO2 replica pistols.

If you want a straightforward CO2 plinker that’s efficient on gas and easy to shoot, the STI Duty One GNB delivers exactly that without any fuss.
