It is made from a strong polymer and sturdy steel feed spring making it a mighty fine magazine that will last you a long time. This magazine can hold approximately 100 BBs so you have plenty of shots available if you opt for semi-auto firing, but if you prefer full spraying, this large magazine will surely have enough BBs in it so you can hit your target, or at least we would hope so...
