The AR-180 vs Sig Spear LT
This video compares the AR-180 and the Sig Spear LT, highlighting their shared lineage from Eugene Stoner's designs. While both utilize a short-stroke gas piston system and rotating bolt, they differ significantly in construction materials and modern features. The AR-180, a civilian variant of the AR-18, features stamped sheet metal construction for cost-effectiveness, while the Spear LT uses machined aluminum for a more robust and modular platform. The comparison emphasizes the evolution of firearm design from the AR-180's foundational concepts to the Spear LT's contemporary ergonomics and accessory integration.
