Dead Air DA301 Flash HiderBlack with 1/2"-28 tpi Threads & 2.70" OAL for 5.56x45mm NATO Sandman Series, KeyMod Equipped Nomad-30 & Primal Suppressors

The Dead Air DA301 flash hider is a 1/2"-28 TPI muzzle device built for 5.56x45mm NATO rifles that need reliable flash reduction without the acoustic signature issues that plague traditional designs. If you're running a modern AR-15 with a suppressor in your kit—whether for precision work, hunting, or tactical training—this flash hider bridges the gap between bare muzzle and suppressed fire. The DA301's equal-length tine design eliminates the "ping" that makes some flash hiders unpopular at the range, and it threads directly onto any mil-spec 1/2"-28 barrel.

Dead Air engineered this hider specifically to work seamlessly with their Sandman Series suppressors and other KeyMo-equipped cans, including the KeyMicro Wolfman, so swapping between suppressed and unsuppressed configurations takes seconds. The pre-drilled pin and weld hole at the 6 o'clock position gives you the option to permanently attach it if your local laws or barrel length require a fixed muzzle device. Built from 4140 heat-treated alloy steel and finished in black nitride, it's tough enough for hard use and runs at 4.08 ounces—light enough that you won't notice it on the gun.

Carbon lock is a real headache when you're trying to swap suppressors in the field. Dead Air's design keeps the suppressor from seizing onto the flash hider, so you can remove it cleanly even after heavy shooting sessions. At 2.70 inches overall length, it sits proportional to most AR barrels without looking or handling awkwardly. Whether you're building a lightweight hunting rifle, a precision .223 range gun, or a duty-ready platform, the DA301 is a straightforward, no-fuss solution that plays well with suppressor-equipped setups.
