Handy little tool for more quickly adjusting original SP1 / M16A1 front and rear sights. It doesn't always work exactly as advertised since it (sometimes) still needs a separate process for depressing the plunger.. but regardless, its still way easier to adjust sights with this tool vs not having one.
Note: M16A1 and M16A2 sight tools are not interchangeable. Two different sizes.
