Over the years in the firearms market the move hasn’t been towards innovation in certain aspects but, refinement of the AR-15 platform and its cartridges. Seeking to optimize the platform. With this refinement of the platform it has turned the AR-15 from a Whiskey with full body and nice finish to a Whiskey with a full body, subtle notes of flavor with a smooth finish. Hornady looks to take advantage of these refinements by wrapping them all up in their new 6mm ARC (Advance Rifle Cartridge) round.
