Grenade Launcher - Attached

Attached

Since grenade launchers require relatively low internal pressure and only a short barrel, a lightweight launcher can be mounted under the barrel of a traditional rifle. This reduces the weight the soldier must carry by eliminating the grenade launcher's buttstock and makes the grenade launcher available for use at a moment's notice.

Underbarrel tubes generally have their own trigger group; to fire, one simply changes grips, disengages the safety, and pulls the trigger. In Western systems, the barrel slides forward or pivots to the side to allow reloading. Soviet/Russian launchers are instead loaded from the muzzle, with the cartridge casing affixed to the projectile in the style of a mortar shell. For aiming, attached grenade launchers typically use a separate sight attached to the rifle's frame alongside the iron sights, or attach a flip-up sight directly to one of the rifle's sights.

Examples of modern attached grenade launchers are the M203, GP-30, AG36, and FN40GL which mount to service rifles.

A late development is the 3GL from Metal Storm. As with most Metal Storm products, this weapon contains three electrically ignited grenades stacked front-to-back in a single tube to eliminate reloading.

Famous quotes containing the word attached:

    Publishers are notoriously slothful about numbers, unless they’re attached to dollar signs—unlike journalists, quarterbacks, and felony criminal defendents who tend to be keenly aware of numbers at all times.
    Hunter S. Thompson (b. 1939)

    Well, most men have bound their eyes with one or another handkerchief, and attached themselves to some of these communities of opinion. This conformity makes them not false in a few particulars, authors of a few lies, but false in all particulars. Their every truth is not quite true. Their two is not the real two, their four not the real four; so that every word they say chagrins us and we know not where to set them right.
    Ralph Waldo Emerson (1803–1882)

    However closely people are attached to one another, their mutual horizon nonetheless includes all four compass directions, and now and again they notice it.
    Friedrich Nietzsche (1844–1900)
