Key Features

• Faux Suppressor Barrel – The 16.25-inch non-threaded barrel wears an oversized shroud that mimics a suppressor, giving the GSG-16 a tactical look while keeping the overall length compact. Why it matters: you get the aesthetic of a suppressed rifle without NFA paperwork or tax stamps.
• Collapsible Stock with Storage – The synthetic stock adjusts for length of pull and houses a clever compartment inside the buttpad for spare magazines or cleaning gear. Why it matters: you can carry extra ammo or tools without adding a pouch or bag.
• 22+1 Round Capacity – The included 22-round magazine lets you stay on target longer between reloads, perfect for steel challenges or plinking sessions. Why it matters: more rounds downrange means less downtime and more fun.
• Picatinny Optics Rail – A full-length rail on the receiver accepts red dots, scopes, or iron sight backups. Why it matters: you can tailor the sighting system to your shooting style—no gunsmith required.
• Adjustable Sights – Rear sight is adjustable for windage and elevation, with a front post that’s easy to acquire. Why it matters: you can zero the rifle out of the box without buying aftermarket sights.

Who It’s For

This rifle is ideal for budget-conscious shooters who want a .22 LR that mimics the ergonomics and handling of a modern tactical carbine. It’s also a strong choice for new shooters learning fundamentals on a low-recoil platform, and for anyone who burns through bricks of .22 every range trip.

Pros / Cons

• Pro: Extremely affordable per round—.22 LR ammo costs a fraction of 9mm or .223, so you can train for hours on a $20 box.
• Pro: Lightweight at 5.1 lbs, easy to carry all day or hand to a younger shooter.
• Con: The non-threaded barrel means you cannot attach a real suppressor or muzzle device without aftermarket modification—if you need that, look for the threaded version.
• Con: The polymer receiver and stock don’t have the same durability as an aluminum chassis, but they keep the weight and cost down.

FAQ

Does the ATI GSG-16 accept standard Ruger 10/22 magazines?

No—the GSG-16 uses its own proprietary 22-round magazines. They are not cross-compatible with 10/22 or M&P15-22 mags. Spare magazines are available from ATI and GSG.

Is the barrel threaded for a suppressor?

This specific model has a non-threaded barrel with a faux suppressor shroud. If you need a threaded barrel for a real suppressor, look for the GSG-16 model with a threaded barrel (sold separately).

What kind of accuracy can I expect at 50 yards?

With quality high-velocity .22 LR ammunition, most shooters report 2–3 MOA groups at 50 yards from a rest. The adjustable sights and Picatinny rail help you dial in for tighter groups.

Does the collapsible stock lock securely in place?

Yes—the stock has a positive locking button that engages at each adjustment position. There is no wobble when locked, and the storage compartment door snaps shut firmly.

Is this rifle legal in all 50 states?

The GSG-16 is a semi-automatic rimfire rifle with a 16.25-inch barrel and collapsible stock. It is legal in most states, but check your local laws regarding magazine capacity—some states limit magazines to 10 rounds. A 10-round magazine version may be available.
