Original U.S. Modern Inert M84 Stun Grenade with Both Primary & Secondary Pull Rings

Original Item. Only One Available. The M84 is a stun grenade ("flashbang") used by the United States Armed Forces and SWAT teams throughout the United States. The M84 features a pyrotechnic metal-oxidant mix of magnesium and ammonium inside a thin aluminium case, contained within a perforated cast steel body. Unlike the high explosives (HE) used in traditional ordnance, the pyrotechnic charge produces a subsonic deflagration, not a supersonic detonation, minimizing the blast effects. Like all deactivated ordnance, this grenade is Not Available for Export.

This example of the M84 is in very good condition with both the primary and secondary pull rings, the triangular example acting as a safety. The secondary pull ring is a bit loose and will come out easily. There is a green band painted in the center, and there are several markings including:

The bottom half has only one part marked, U.S. PAT. / 5,824,945. The grenade retains its spoon which is painted brown at the end.

A good example of a modern stun grenade, perfect for display.

On initiation, the auditory and visual elements of the deflagration are permitted to escape via the perforations in the cast outer body. This design minimizes the risk of collateral damage due to flame, blast, and unconsumed fragments of the inner case.

Upon detonation, it emits an intensely loud "bang" of 170–180 decibels and a blinding flash of more than one million candelas within 5 feet (1.5 meters) of initiation, sufficient to cause immediate flash blindness, deafness, tinnitus, and inner ear disturbance. Exposed personnel experience disorientation, confusion and loss of coordination and balance. While these effects are all intended to be temporary, there is risk of permanent injury. Consequently, the M84 is classified as a less-lethal weapon.

It is intended to be thrown into enclosed spaces to distract and temporarily incapacitate enemy personnel for easier capture, or when risk of collateral damage during urban warfare or hostage rescue operations contravenes the employment of traditionally lethal and destructive fragmenting high explosive ordnance.

While the M84 is generally incapable of igniting paper or cloth, it can still ignite extremely flammable liquids or vapors (such as concentrated gasoline or ether fumes) in the immediate area of the grenade.
