Adjusting the fit of iron sights in their dovetails typically requires complex jigs or a hammer, punch and gun cradle, which can be awkward to handle or take to the range. The Wyoming Sight Drifter helps avoid such complications and is not much larger than a common ink pen.
The ingenious design uses a simple extension spring attached to steel sections that feature finger grooves and end pieces of nylon and brass. Simply hold either end against the side of a dovetailed sight with one hand and use the other hand to momentarily pull up on the spring, then let go. Once the stored kinetic energy is released, the two steel sections will collide, impacting the end in contact with the sight and drifting it. The force is easily controlled by how far the spring is stretched, and the nylon and brass are non-marring.
