IWI QD Muzzle Brake Features The IWI QD Muzzle Brake is machined from steel and finished in a durable black oxide coating that stands up to repeated firing without losing its function or appearance. Its quick-detach design allows the brake to double as a suppressor mount so shooters can move between an unsuppressed muzzle brake and a mounted IWI suppressor without swapping parts. The brake s port geometry redirects propellant gas to counter muzzle rise and felt recoil which keeps the sights on target for faster more accurate follow-up shots. Threaded at 1/2x28 it installs directly onto standard 5.56 NATO AR-15 pattern barrels and the left-hand quick-detach interface locks the brake securely in place so it does not loosen or walk off under sustained firing. Because the brake integrates with IWI s own quick-detach suppressor system shooters get the flexibility to switch configurations in seconds without tools once the mount is installed. At 6.4 ounces the brake adds minimal weight to the front of the rifle while still delivering a real reduction in muzzle climb during rapid strings of fire. The steel construction and black oxide finish resist corrosion and wear from repeated mounting and dismounting so the quick-detach interface keeps indexing properly over years of use. IWI s decades of experience building rifles for military and law enforcement use back the engineering behind this muzzle device giving shooters confidence in a component built to the same standards as the rifles it was designed around. For AR-15 shooters who want the option to run suppressed or unsuppressed without changing hardware this brake is a practical durable choice that simplifies switching between range sessions and suppressed work in the field.
