GSG16 stick magazines are pretty reliable if you load them to 20 rounds. If you load them to the advertised 22 round capacity or shove a 23rd in, they would frequently have feed issues as the magazine bulges outwards. I've had thousands of rounds through them with no issues when loaded to 20, as the GSG16 was my go to gun for introducing new shooters to the sport.
Ive shot tens of thousands of rounds rotating through a dozen or so of them, never had a single issue that was mag related. My all time favorite 22 mag. I could see dropping them repeatedly on concrete causing issues eventually though. The drum mags however were totally dogsh!t.
All mine warped enough that they wouldn't feed reliably. Worst mag ever imo. good for year..then trash. (gsg-15)
That's a good idea!
