Maxim Defense QD Muzzle Device - 1/2-28 - Stainless Steel

The foundation of any suppressor-ready Maxim Defense muzzle setup, the QD Flash Hider in 1/2x28 provides a precision-threaded, aerospace-grade base that accepts HUB QD Adapters for rapid suppressor attachment without sacrificing muzzle control between runs.

The Maxim Defense QD Flash Hider is a stainless steel quick-detach muzzle device for 1/2x28 threaded barrels, engineered for fast, repeatable suppressor mounting and standalone flash mitigation.

Machined from 17-4 H900 stainless steel, this flash hider provides the structural foundation for the Maxim Defense modular muzzle ecosystem. The precision 1-16 Acme QD thread accepts HUB QD Adapters for tool-free suppressor transitions with consistent indexing and secure lockup. Without a suppressor attached, it performs as a standalone flash hider, reducing visible signature at the muzzle during unsuppressed fire. The Richter C3B coating keeps threads smooth across repeated attachment cycles and makes carbon removal straightforward after extended range use, which matters for high-volume shooters who run the same device on multiple platforms.

Direct fit for any 1/2x28 threaded barrel. Serves as the base component for the full Maxim Defense QD muzzle system, including the Hate Shroud and HUB QD Adapters.

17-4 H900 stainless steel delivers a hardness and strength-to-weight profile that outperforms standard carbon steel at elevated temperatures. The Richter C3B finish adds a layer of corrosion and heat resistance that keeps the device serviceable through heavy round counts without performance degradation.

The right starting point for any 5.56, .223, or compatible build that may run a suppressor now or in the future. Also a practical standalone flash hider for unsuppressed AR-15 carbines and patrol rifles where quick-detach capability is a worthwhile investment regardless of current suppressor ownership.

Maxim Defense backs the QD Flash Hider with their manufacturer warranty, building suppressor-ready muzzle devices to the same standards as their complete rifle systems.
