Why This Matters: A loose or missing rear sight set screw can cause your sights to shift during firing, destroying your zero and accuracy. This OEM screw ensures your rear sight stays locked in place shot after shot.

Installation Tip: Apply a small amount of thread locker (blue Loctite) when installing to prevent the screw from backing out during use. Torque to factory specifications.
