"The 5.45 Ergonomic magazine is a top-tier mobility attachment that provides a significant +2.0% flat movement speed bonus. It features the fastest reload in its class (2.5s) and a substantial +15% aim speed buff, making it perfect for aggressive SMG and AR playstyles. While it doesn't offer the depth of a drum, its contribution to handling and rotation speed makes it a favorite in the competitive meta. It is the definitive choice for players who rely on kiting and aggressive repositioning."
