Otis AR Lock Block, Black

Facilitates the expedited removal and installation of barrels and handguards, while enabling the effortless handling of seized barrel nuts. The tool is secured in a standard bench vise and locks into the barrel extension, preventing twisting and minimizing the risk of surface damage. To address variations in internal receiver dimensions available in the market, it incorporates a bronze bushing, allowing compatibility with slightly smaller internal specifications. The tool engages its locking lugs into the barrel extension, thereby relieving tension on the receiver and transferring it to the extension itself. Reduces stress on the receiver by activating the locking lugs Engineered for Mil-Spec receivers The bronze bushing is compatible with the majority of ARs models Compatible with the majority of standard table or bench vises Constructed from 1018-grade steel, featuring a manganese phosphate coating for enhanced corrosion resistance and durability
