A flash hider that utilizes the Torque Lock technology for your HUXWRX or OSS suppressor
The Flash Hider-QD 556 is designed to mitigate flash when unsuppressed. This flash hider utilizes Torque Lock technology that self-tightens it to your muzzle with every round fired. Flash Hider-QD 556 is compatible with Flow 556k, HX-QD 556k, 556, 762, 762 Ti and Magnum Ti suppressors.
Muzzle device length is 2.3 and length added to barrel is 1.7 inches.

Thanks to the crew at Rooftop for sending this flash hider in such expeditious fashion! I’ve been looking for this Huxwrx part for a while and Rooftop was the only outfit that had them in stock. Ordering was simple, shipping was quick, correct product arrived ahead of expectation and will be an awesome final piece to my Socom Block 2 rifle.

Necessary to run the flow 556. Definitely recommend purchasing the blastphemy to protect the threads when not running suppressed.

Very, very little flash, works great. Machined nice, well made, and looks sweet. Not to mention super fast shipping!
