The TYR Tactical® Front Wing 5.56 Mag Adapters come as a left and right set. Each holds a single mag and attaches to the side of your front flap Velcro tabs. The low profile minimalist design does just what it needs to, without excess weight, and without using up valuable molle space on your carrier. The Velcro tabs mount neatly under your front flap and sit under your cummerbund, keeping them close to the body reducing overall system bulk. The Mag adapters work with any TYR Tactical® carrier that supports a kangaroo style front flap.
