This is a factory-manufactured GSG-16 .22LR 10 Round Magazine. Its advanced polymer construction will protect it from the most extreme conditions. With this GSG-16 magazine, the exposed frame counter reveals how many rounds are left in the magazine. Also, say goodbye to sore thumbs after cramming rounds on top of one another – the .22LR spring-assist allows you to pull down and load ammo. With the GSG-16 carbine, there’s every reason to order a few extra magazines.
