The ATI GSG-16 .22LR semi-auto tactical rifle brings modern, modular ergonomics to affordable rimfire shooting. Built on a proven .22LR operating system, the GSG-16 delivers the tactical look and handling of a centerfire platform in a lightweight, fun-to-shoot package that's ideal for plinking, training, and introducing new shooters to tactical rifle fundamentals. At just 5.84 lbs unloaded, it's easy to handle for extended range sessions or backyard practice.
The GSG-16 sports a collapsible stock that does double duty—it collapses from 34¼ inches to 28½ inches for compact handling, and doubles as built-in magazine storage so you can keep spare rounds close. The redesigned MLOK handguard gives you modern mounting flexibility for lights, lasers, or grips. An ambidextrous charging handle lets you run the gun comfortably from either side, and the simplified front and rear sights are engineered for fast target acquisition. The rifle ships with a 22-round magazine and is compatible with GSG-5/522 stick and rotary magazines, so you can mix and match your existing .22LR rimfire magazines.
Chambered in .22LR (high-velocity 1260 fps ammo recommended), the GSG-16 offers reliable, cost-effective trigger time without breaking the bank. Its 16¼-inch barrel with 6 grooves and 5.5 lb trigger break provide the control and feedback serious shooters expect. Whether you're zeroing a new optic setup, running carbine drills on a budget, or just having fun at the range, the GSG-16 is a versatile rimfire that earns its place in any shooter's battery.
