Noveske M16 A2 Flash Hider w/1/2x28 Crush Washer 0. The Flash Hider's sleek contour blends the device seamlessly into the existing Noveske Linear Comp M16-A2 body and threads onto standard A2 shrouds with no need for modification or aftermarket attachments. The Flash Hider features smooth straight sides which reduce dust signatures when firing in DPR or SBR fashion and utilizes a layer of proprietary carbon fiber with an ion-nitride finish for maximum durability and strength. The Flash Hider works best with a threaded barrel with a 1/2-28uniform thread pitch. Once threaded the barrel needs to be chamfered and cleaned before installing the device leaving the threads chamfered and clean for a snag-free fit. Soft thread-lockant material and crush washer are included. Check manufacturer recommendations to ensure a proper fit.
