HX30-AR15S2-GRY) brings the company’s PolyHex2 advanced composite construction to a full-capacity 30-round configuration for AR-15, M4, and M16 pattern rifles chambered in .223 Remington/5.56x45mm. Finished in gray with a contrasting orange follower for at-a-glance loaded status, it uses Hexmag’s redesigned feed lip geometry and stripper clip guides to speed up reloading, while a deep catch pocket and heat-treated stainless steel spring keep it stable through extended storage. The patented Tool-Less design allows fast floorplate removal for field cleaning and HexID color customization. It’s backed by a lifetime warranty and made in the USA. For Hexmag owners of an AR-15/M4/M16, this AR-15 magazine is a durable, full-capacity spare.
