The Real Avid AR-15 Smart Lock Bore Guide is an innovative tool designed specifically for AR-15 cleaning. This clever device locks the AR-15 upper open while aligning cleaning rods perfectly within the barrel. The pivot-locking arm securely holds the upper in an optimal position for effective bore cleaning, ensuring that the chamber and bore are protected from damage caused by cleaning rods. With its smart design, it minimizes the entry of solvents and debris into the action, making the cleaning process more efficient and effective.
