The first time we had a glimpse of the upcoming Mag17 from CAA Airsoft Division was almost a month ago. And now they have released a video presentation which answers some of our questions. There is no pop-up pin and the indicative window is not transparent, since if it is, then it should show the BBs inside. The features are mainly cosmetic with the exception of the build quality and 140-round capacity which should be good for MilSim players.
Ho of VProduction sent us the photo link of an upcoming product from the CAA Airsoft Division. He never mentioned that name of the product so we had to do some quick digging on our own by going to the CAA Tactical website which shows it to be the Mag17, which is their polymer magazine with a window and pop-up pin magazine indicator.
