GSG Firefly Mag Upgrade May 22, 2026 Reviewer: Maxwell Hille from Saint John, WA United States   Took a little tuning on the follower to move freely up and down the mag body, but took a pistol I was never fond of and made it pretty slick! Improved feeding quite noticeably, definitely recommend this! Don hesitate to pick this up! Was this review helpful to you?

16 round GSG Firefly magazine upgrade January 12, 2026 Reviewer: Don Fitzgerald   Had to use Emry Board and file all sides a little. Follower would get stuck last 1/4 to the top, you could push it up or down but wouldn't slide all the way. Little sanding with Emry Board fixed this. Works fine now. Was this review helpful to you?
