Our quick-mounting suppressor for the Heckler Koch UMP submachine gun significantly outperforms other entries for this weapon system. Available in either 40S&W or .45ACP, both versions feature our Posi-Lock quick detach mount (patents pending), which is simple to operate and once locked in place cannot inadvertently open or rotate orientation. On special order, this suppressor can be supplied with a steel 5/8-24 threadmount endcap for use on .45acp or .44 special subguns and carbines with threaded barrels.
