This 4-in-1 tool from Real Avid® gives you full access to your Glock® pistol for maintenance and modification. Ergonomically designed and textured for grip, the 4-in-1 Glock Tool features a push-button release for each of the four individual tools. The 3/16” bit driver allows users to remove and replace the Glock front sight. A .05” Allen wrench is also included for adjustments to most aftermarket target sights and lasers. On the lower receiver of your Glock pistol, the 4-in-1 tool provides the ability to detail strip for deeper cleaning. The 3mm punch is perfect for driving out retaining pins, while the small flathead screwdriver assists in removing the locking block and slide lock spring.
