Features: brand new and high quality Primarily made of aluminum alloy. The advantages of aluminum alloy are good corrosion and oxidation resistance and durability. The rest of the parts are made of iron for improved strength. These materials were chosen to improve the overall durability of the tool and extend its usable life. Our front push block is made of iron, which will not easily break when the gun is removed, unlike others that use powder metallurgy technology. Our handle is also well-designed to allow the user to easily adjust the position of the front push block. Our base stability is better than products that use an unstable circular base. Our rectangular design supported by an intersecting adjustable plate is stable during the sight adjustment process, preventing damage to your barrel. The user can control the height of the base using the screw to position your slide and rear sights at the proper height. Our base can also be bolted to a workbench for greater stability. Most other sight blocks jitter up and down during adjustment, so we added a fixed track above the sight block to fix the position of it sight tool so that it remains stable and does not damage the barrel. Most products use a design with slide clamps on both sides to fix the gun. This design is unstable and easily scratches the barrel. Our sight tool has a movable slide side clamp on the left side and a fixed plate on our right side. This is more stable and will not scratch the barrel.
