The grenade body of steel is essentially spherical in shape. The body is empty, i. There is a hole in the base of the body. This vents the gases generated from the fuze igniter and permits removal of residual metal that remains in the grenade body from the igniter case.
The grenade body may be recovered and reloaded with a new fuze and safety clip. Hand grenade practice fuze M is a pyrotechnic delay-igniting fuze. The body contains a primer and a pyrotechnic delay column. Assembled to the body are a striker, striker spring, safety lever, safety pin with pull ring, safety clip, and igniter assembly.
Older models do not have the safety clip. The split end of the safety pin has an angular spread or a diamond crimp. The hand grenade safety clip is designed to keep the safety lever in place, should the safety pin be unintentionally removed from the grenade. It is an additional safety device used in conjunction with the safety pin. Older models have the safety clip assembled to the grenade and positioned around the safety lever. Safety clips from expended grenades may be reused, provided that visual examination indicates the clip is not damaged or distorted.
Delay practice hand grenade M69 is the practice version of the M67 fragmentation delay grenade.
Release of the safety clip and removal of the safety pin permit release of the safety lever. When the safety lever is released, it is forced away from the grenade body by a striker acting under the force of a striker spring. The striker rotates on its axis and strikes the percussion primer. The primer emits a small, intense spit of flame, igniting the delay element.
The delay element burns for 4 to 5 seconds, then sets off the igniter. A loud report, like that of a firecracker, and a puff of white smoke follows.

The M67 is a fragmentation-based hand-grenade utilized to supplement infantry actions in the field. The hand grenade concept is an ancient one, with roots dating back centuries. The principle behind the device is to inflict area damage to entrenched personnel by way of force-thrown high-velocity fragments distributed in a uniform pattern. The M67 is currently in service with US military forces among others and has proven a capable area-effect weapon.
The M67 was selected as the replacement infantry hand grenade for the M61 series used in the Vietnam War. The M67 is made up of a 2. The grenade is fitted with a an internal M series fuze that ignites the explosive charge within. The explosion disintegrates the grenade casing itself, which in turn becomes the fragmentation component of this hand grenade.
There is a four-to-five second window for the operator to throw the grenade at the target area based on the delay detonation cycle built into the device. The actual detonation cycle is activated when the spring-loaded safety lever separates from the grenade while in flight. An internal firing pin then hits against a percussion cap and ignites the M fuze.
This action is preceded by the operator having removed the pin to begin the detonation process in full. Reportedly, the pin can be inserted back into a live grenade so long as the safety portion of the grenade is still in place. Range is dependent on the thrower while the lethal damage radius is reported to be approximately Such is the value of these little hand-held and thrown battlefield implements.
In Canadian service, the M67 falls under the designation of "C13".★ How to Re-Use Grenade Fuze ★

Scroll Prev Top Next More.Grenadesmall explosivechemical, or gas bomb that is used at short range. The word grenade probably derived from the French word for pomegranatebecause the bulbous shapes of early grenades resembled that fruit.
Grenades came into use around the 15th century and were found to be particularly effective when exploded among enemy troops in the ditch of a fortress during an assault. They eventually became so important that specially selected soldiers in 17th-century European armies were trained as grenade throwers, or grenadiers see grenadier. After aboutgrenades were virtually abandoned because the range and accuracy of firearms had increased, lessening the opportunities for close combat.
Grenades did not come back into use on an important scale until the Russo-Japanese War — The grenades most commonly used in wartime are explosive grenades, which usually consist of a core of TNT or some other high explosive encased in an iron jacket or container. Such grenades have a fuse that detonates the explosive either on impact or after a brief usually four-second time delay that is long enough for the grenade to be accurately thrown but is too brief for enemy soldiers to toss the grenade back once it has landed among them.
A common type of explosive grenade is the fragmentation grenade, whose iron body, or case, is designed to break into small, lethal, fast-moving fragments once the TNT core explodes. Such grenades usually weigh no more than 2 pounds 0. Explosive hand grenades are used for attacking the personnel in foxholes, trenches, bunkers, pillboxes, or other fortified positions and in street fighting. Another major class is chemical and gas grenades, which usually burn rather than explode.
This class comprises smoke, incendiary fire-settingilluminatingchemical-warfare, and tear-gas grenades. The latter are used by police for riot and crowd control. Several uses may be combined, as in a white phosphorous grenade that has smoke, incendiary, and antipersonnel effects. Grenades can be launched from the muzzle of a rifle either by the force of a cartridge or by the expanding gases of a blank cartridge. Such grenades usually have long, streamlined bodies, in contrast to the round shapes of hand grenades.
There are also small-arm grenade rounds, shaped like bullets but of much greater diameter usually 40 mm.
These contain their own low-energy propellant charges and are shot from special large-bore launchers similar to shotguns or from launchers attached to infantry assault rifles. Another type of grenade is the antitank grenadewhich contains a special shaped-charge explosive that can pierce even the heavy armour of a tank. Since these are usually delivered by small rockets launched from shoulder-held tubes, they are commonly referred to as rocket-propelled grenades.

Hand grenades can be classified as: Fragmentation. These grenades are used to produce casualties by high velocity projection of fragment. Historically, the most important hand grenade has been the fragmentation grenade, which is the soldier's personal indirect weapon system. Fragmentation grenades are fused with either impact detonating or delay detonating fuzes composed of a striker, primer and delay charge detonator. A booster may be included. A safety lever, curved to conform to the shape of the grenade body, is hooked to the top of the fuze.
The lever is held in place by a safety pin pull ringwhich protects the striker from action of the striker spring. Safety pin removal is required immediately before the grenade is thrown. This grenade is used to provide illumination of terrain and targets.
Because the illuminant compound burns with a very hot flame, this type can also be used for incendiary purposes against flammable targets. A typical illuminating grenade is similar in size and function to burning-type chemical grenades.
It consists of three basic components: a thin, sheet-metal body, an illuminating charge, and a special, igniter-type fuze. The igniter consists of a quick-match contained in a bushing. The illuminating charge consists of a pyrotechnic composition, a first-fire composition and an igniter charge. These grenades are used for incendiary, screening, signaling, training, or riot control purposes. Burning-type grenades are usually fitted with igniting fuzes which function with a 1.
Functioning of the fuze ignites the first-fire starting mixture which ignites the filler. The burning filler creates sufficient pressure to blow tape covering the emission holes gas ports free and allow the chemical agent riot control gas, smoke to escape. Standard protective masks filter particles but will not supply oxygen. Therefore, burning grenades will not be used in enclosed or confined spaces.
Bursting-type grenades are fuzed with delay fuzes which contain high-explosive detonators. The detonators rupture the grenade body and disperse the filler tear gas, white phosphorus.
Although this type of grenade functions by bursting, it creates the same effect as burning grenades. The current U. CS irritant gas tear gas may be employed in a combat zone with the approval of a higher authority.
The Secretary of Defense may authorize the use of CS to protect and recover nuclear weapons.

CS may be used on military installations domestic and overseasembassy grounds, and so forth, in war and in peace. The U.The military of the United States has used many of different types of hand grenades since its foundation. Presented on this page is a basic overview. The Mk II had a grooved exterior originally intended to aid fragmentation of the grenade.
Inert Ordnance/ Rounds
However, later studies showed that this design has no effect on fragmentation, though it does provide a non-slip surface that improves grip. The filling was either EC blank fire powder approx. Unlike the Mk IIthe Mk III also written Mk 3 was a cylindrical grenade designed to be used as an offensive weapon for clearing rooms, trenches, and other enclosed spaces i. A concussion grenade, the Mk III series was designed to incapacitate through the pressure and impulse produced by the explosion.
The M26 series is in many ways an upgrade in basic principle of the Mk II : a similarly shaped, but not visibly ribbed, fragmentation grenade. The M26 has a filling of Composition B contained within a sheet steel two-part outer shell which covers a prenotched fragmentation coil inner liner.
The use of the inner liner creates a highly predictable fragment pattern and casualty radius. The grenade was found to have problems with incomplete detonation of the filler, and the M26A1 featured a tetryl booster to ensure complete detonation. Similar in format to the M26the M33 is a spherical fragmentation grenade also filled with Composition B explosive. Unlike the M26, the inner wall is prescored and does not contain a fragmentation coil.
The M67 was part of a similar PIP, and is identical to the M33 with the exception of the additional safety clip for the spoon of the grenade on the M The M33A1 is the impact version of the M33, using the M electrical impact fuze in place of the normal delay fuze.
At an unknown time the M33A1 was redesignated as the M The M68 is the same as the M59, with the exception of the additional safety clip.
The grenades are "stackable," meaning up to three can be connected to increase blast power. The base grenade has a non-removable, 3. The ET-MP allows soldiers to choose between fragmentation and blast overpressure effects by flipping a switch. It also has improved safety, being the first Insensitive Munitions -qualified lethal grenade in the Army's portfolio with an electronic fuse, or delay mechanism, instead of a mechanical fuse that can be narrowed down into milliseconds and, until armed, will not be able to detonate.
The grenade is designed for ambidextrous use, so the same arming procedure is used for either hand, whereas the M67 required a different procedure for left-handed use. Research for the ET-MP grenade began inwith entry expected in In September the United States standardized a Molotov cocktail -style device that was nominally designated as a "grenade". It consisted of a pint-sized clear glass bottle with a crimped metal cap.
It was dubbed "frangible" because it was made of glass, which is brittle and easily broken. Most fillers were liquid compounds selected because they were activated by exposure to the air, thus not requiring a detonator. FS was a mixture of sulfur trioxide and chlorosulfuric acid that created a heavy, acrid screening smoke. The M8 is used for signaling and screening purposes, and since it works by burning the HC for its effect, it can also be used as an improvised incendiary device.
The Model was modified for a US Navy SEAL requirement with a greater burning rate, meaning a greater smoke output but a shorter overall burning time.
The M15 is a white phosphorus smoke grenadenicknamed Willie Peter or Willie Pete for white phosphorusused for screening and signaling purposes.
It is cylindrical, but with rounded edges compared to those of the M8. The M16 was a colored version of the grenade that was originally available in red, orange, yellow, green, blue, violet, and black smoke versions. This was later simplified to red, yellow, green, and violet. The M34 grenade was a variant of the M15 designed to be usable as a rifle grenade using the M2 series of grenade launching adapters, and was ribbed to give the fins better grip on the grenade body.In stock.
Original Item: Only One Available. Totally inert and demilitarized according to BATF guidelines with hollow body and inert fuse. This grenade cannot be converted to an explosive devise and is not available for export. M67 grenade, which was first fielded during the Vietnam War and still current today. It is unmarked on both the body and fuze, and has been painted OD green over the original blue color, which indicates it is a practice grenade.
It has an empty detonator factory attached to the fuze, with a hole drilled through the bottom of the detonator to show that it is empty. There is also a large hole in the bottom of the grenade body, further indicating that it is inert, which allows the practice fuse "pop" to be heard when used in training.
The M67 grenade has a spherical steel body that contains 6. It uses the M pyrotechnic delay fuze. The M67 grenade weighs 14 oz g in total and has a safety clip to prevent the safety pin on the grenade from being pulled accidentally.
The safety pin prevents the safety lever, or "spoon" on the grenade from moving and releasing the spring-loaded striker which initiates the grenade's fuze assembly. The M67 is typically known as a "baseball" grenade, because it is shaped like a ball that can be easily thrown. Other variations include the "pineapple" grenade and the World War 2 era "stick" grenade. The M67 can be thrown 30 to 35 metres 98 to ft by the average male soldier.
Its fuze delays detonation between 4 and 5 seconds after the spoon is released. Steel fragments not to be confused with shrapnel are provided by the grenade body and produce an injury radius of 15 metres 49 ftwith a fatality radius of 5 metres 16 ftthough some fragments can disperse as far out as metres ft.
