Firing the .408 Chey-tac round, the XM408 ASA from THOR Global Defense utilizes a 30″ fluted Krieger match barrel and a unique chassis to help mitigate recoil, allowing for quicker follow up shots. Additionally, this is a lot of gun so it incorporates a carry handle to help facilitate getting it in place as well as an adjustable cheek piece to enhance ergonomics. The stock is also fully adjustable and manufactured from hardened aluminum.
The .408 Cheyenne Tactical cartridge was envisioned to fill a role in between the .338 Lapua Magnum and .50 BMG rounds. It is intended for use in the anti-personnel, anti-sniper and anti-materiel roles and features a (supersonic) precision range of 2,200 yards (2,000 m).
