Seems to work fine in both of my Geckos, A little looser fit than the custom magazine may require using the Strong magazine holder in the Gecko.
I'm using these with my Gecko, they work great! Now I just wish I had ordered more to start with!
This mag is a great fit for the Gecko blaster. Smooth feeding, and durable. I have experienced no issues with using the worker mags. I can recommend this item to feed the Gecko.
It feeds well, feels and looks great. Same quality the hobby has come to expect from worker.
