ATI GSG-16 .22LR Rifle - 16.25" Barrel, Mint Green Finish, 10-Round Magazine

The ATI GSG-16 .22LR rifle is a modern take on a tactical .22 that's built for shooters who want accuracy, modularity, and fun without breaking the bank. This semi-auto .22LR carbine pairs a lightweight polymer receiver with a 16.25" barrel and comes finished in eye-catching mint green—a rifle that looks as good at the range as it performs. Whether you're zeroing in your marksmanship, running drills, or just enjoying an afternoon of affordable trigger time, the GSG-16 delivers the handling and features you'd expect from a modern platform rifle in a caliber that won't drain your ammunition budget.

The GSG-16's design prioritizes shooter control and adaptability. The collapsible stock adjusts overall length from 28.5" to 34.25", fitting different body sizes and shooting positions, and doubles as storage for spare magazines. The redesigned forend integrates both Picatinny rails and M-LOK slots, giving you multiple options to mount optics, lights, or other accessories without hunting for adapter plates. An ambidextrous charging handle lets you work the bolt from either side, and the simplified front and rear iron sights are built for quick target acquisition right out of the box.

Built on American Tactical's proven GSG .22 operating system, this rifle handles reliably through thousands of rounds. The 10-round magazine capacity keeps you focused on shooting rather than constant reloads, and the two-position thumb safety is intuitive and accessible. A faux suppressor gives the GSG-16 its distinctive profile while you're shooting unsuppressed—practical aesthetics for a gun that's equally at home at an indoor range or backyard setup.

Is the collapsible stock adjustable for different shooters?

Yes. The stock extends from 28.5" to 34.25" overall length, allowing you to dial in the length of pull that works for your body size and shooting style. It also serves as storage for extra magazines when collapsed.

Yes, it ships with adjustable front and rear iron sights that are optimized for quick target acquisition. You can use these out of the box or mount an optic to the Picatinny rails if you prefer a red dot or scope.
