These punches are specifically designed for the installation, removal, and adjustment of front and rear handgun sights. Made of brass so they will not mar the sight or the gun if you slip. Unique triangular punch faces and heavy-duty bodies make them indispensable working tools for the gunsmith. Can be re-ground to square up the flat after multiple uses. Front Sight Punch has a base width of approximately .280"; Rear Sight Punch has a base width of approximately 0.480". They are sold separately or can be purchased together in a handy Kit. The Small Dovetail Sight Punch (sold separately) has a .230" base width, making it ideal for front and rear sights on compact handguns.
