Engineered to withstand the harshest battlefield conditions on Earth, the NT4 delivers combat-proven decibel reduction, extreme flash suppression, and near-indestructible endurance under sustained fire.

Its heavy-duty internal core is built to handle punishing full-automatic firing schedules without structural degradation or point-of-impact shift. Bearing an official National Stock Number (NSN: 1005-01-437-0324) and finished in a classic black heat-resistant protective coating, this complete turnkey kit includes the QDSS-NT4 suppressor along with a genuine 1/2x28 M4QD flash hider kit for immediate duty or clone-correct builds.
