ASG STI Licensed DUTY ONE CO2 .177 Cal Non-Blowback Airgun, Black

Fully licensed by STI, the black ASG STI Licensed DUTY ONE CO2 Non-Blowback Airgun pairs a heavy metal slide and internal metal barrel assembly with a high-density polymer frame and textured grip panels. Featuring a 4.7-inch barrel and weighing 1.8 pounds, this authentic training sidearm delivers modern combat ergonomics. Running on single 12g CO2 capsules, its non-blowback mechanism sends full pressure behind every round. Firing 0.177 caliber (4.5mm) steel BBs in semi-automatic mode, it reaches a strong muzzle velocity of 407 FPS. Feeding relies on an included 20-round removable drop-free magazine. Factory box contents supply the licensed air pistol, one 20-round steel BB magazine, and an instruction manual.

Specialized proprietary internal parts mean aftermarket mechanical upgrades are not available for this platform. Engineered for maximum speed and accuracy straight from the factory, keeping it running smoothly comes down to routine maintenance and field supplies rather than internal overhauls. To streamline your setup without altering the internal mechanics, keep the factory parts stock while stocking up on extra ASG 20-round steel BB magazines, extra 12g CO2 cartridges, premium steel shot, and a lower-rail tactical flashlight or laser.
