The Heckler & Koch rear sight retaining screw is a genuine OEM replacement fastener engineered for H&K pistols that use a removable rear sight assembly. If your rear sight has come loose, won't hold zero, or you're reassembling sights after maintenance or adjustment, this is the factory-spec screw you need. It's a straightforward, no-nonsense part that does exactly one job—keeping your rear sight exactly where it needs to be.
This isn't a universal screw; it's matched to H&K's tolerances and design. Whether you're a dedicated H&K shooter, a gunsmith, or simply maintaining your pistol to factory standards, using the correct OEM fastener ensures proper fit and function without the guesswork of sourcing aftermarket substitutes.
Stock this in your spare parts drawer, keep it in your range bag, or grab it as insurance if you've lost the original. It's the kind of small part that matters when you need reliable, repeatable sight performance.
