The BEV Block (Barrel Extension Vise) is an all-in-one, compact vise block tool for AR15/M4 assembly operations—from barrel nuts to flash hiders—designed for anyone who wants a solid foundation during builds or maintenance. Made in the USA, it secures uppers and lowers with professional-grade reliability and a touch of practical swagger.
