Owners of the GSG-16 like that it gives an AR-style manual of arms and general handling without the cost or ammunition expense of a centerfire AR rifle. Reliability comments are mixed: many shooters report good runs once the rifle is broken in and cleaned, while others say they had to experiment with ammunition to get consistent cycling, which is common for blowback .22 LR autoloaders.

Ergonomically, the collapsible stock and Picatinny rail are popular for adjusting length of pull and adding optics, and the ghost ring sights get credit for fast target acquisition even without glass mounted. Some shooters feel the synthetic furniture feels lighter than a true centerfire AR platform, which tracks with the price point.

On value, the GSG-16 is generally seen as a fun, budget-friendly way to train AR fundamentals or plink with cheap rimfire ammunition. Aftermarket support is decent for a rimfire clone, though not as deep as the centerfire AR market.
