This short discusses the new Sig Spear Fury, highlighting its development driven by the US Army's need for a round capable of penetrating body armor at 200 yards, a capability the 5.56mm round lacked. The video explains that the Fury is essentially a 6.8mm round, with the Army utilizing a high-pressure variant. A key technical detail mentioned is Sig's proprietary barrel coating, designed to withstand the extreme pressures of this ammunition and prevent premature barrel failure after approximately 1,000 rounds.
