Overview
Built for AR15/M4-compatible rifles, this 30-round polymer magazine is designed for shooters who want quick round-count checks and straightforward maintenance. Transparent windows provide a fast visual reference for remaining ammunition, while the constant-curve internal geometry, four-way anti-tilt follower, and stainless steel spring are included in the design for feeding support. It is optimized for Colt-spec AR15/M4 platforms and also listed for use with a range of other compatible weapons, making it a practical option for range sessions, training, and field carry where magazine status matters. The medium coyote tan finish gives it a subdued look without adding any unsupported claims about durability or performance.
