The Vism Universal Pistol Front and Rear Sight Tool is designed for removal, installation, and adjusting windage of dovetailed sights for most Semi-Auto Pistol slides. It features two separate sight pusher blocks. Each pusher is specifically designed for either front or rear dovetail sights. The pusher blocks are constructed from tool steel. The base platform is adjustable for height to properly align your sights at the proper height for the sight pusher blocks. The adjustable side and top clamps secure the slide in place. Side witness windows on both sides of the tool frame allow you to check for the proper sight and pusher block alignment. The sight tool frame can be bolted to or clamped onto a work surface or clamped onto a vice. It features a heavy duty blue anodized aluminum frame and the sight pusher steel screws have brass bushings for goo bearing surface characteristics and excellent strength.
