The Heckler & Koch Clamping Sleeve (H&K part no. 50984199) is a genuine factory part built for the HK416 platform, fitted to the MR556A1. A clamping sleeve like this one locates and secures a mating component to factory tolerances, so replacing a worn or damaged sleeve with the current H&K part restores the original fit rather than introducing play.
