The M7 grenade launcher, formally rifle grenade launcher, M7, was a 22 mm rifle grenade launcher attachment for the M1 Garand rifle that saw widespread use throughout World War II and the Korean War. The M7 was a tube-shaped device, with one end slotting over the muzzle of the rifle and attaching to the bayonet mount, and the other end holding ...
It consisted of an add-on 22 mm (0.87 in) stabilizer tube and fins that converted a hand-grenade into a rifle grenade. It supplanted the M17 rifle grenade, and was eventually made obsolete by the 40 mm M79 grenade launcher.

M9 rifle grenade being launched from an M1 Garand. The M9 rifle grenade was an American anti-tank rifle grenade used during World War II. The earlier-designed M10 grenade was too heavy to be fired an effective distance by a rifle; the M9 was conceived as a lighter version of that design. (The M10 became part of the evolution of the bazooka.)
The M31 HEAT rifle grenade is a fin-stabilized anti-tank rifle grenade designed in the late 1950s to replace the Belgian ENERGA rifle grenade which was adopted by the US Army and US Marines as an emergency stop-gap measure during the Korean War. Compared to the ENERGA, the M31 is slightly lighter in weight and has a smaller-diameter warhead—i ...

Once the warhead is screwed in, the M17 is fitted onto a grenade launcher adapter, such as the M7 grenade launcher. A special blank .30-06 cartridge is inserted into the rifle, then fired. The M17 will not explode if it lands on sand, water or mud; only solid ground will cause it to detonate. [2]
The rifle grenade propelling cartridges fired a wooden projectile through the barrel to the rifle grenade that upon impact automatically primed the rifle grenade. The Schiessbecher had a short rifled barrel with a caliber of 30 mm (1.2 in ) and a length of 250 mm (9.8 in).
Thus, a 22 mm rifle grenade can easily be as powerful as a 40 mm grenade, in spite of the seemingly smaller size. A 22 mm grenade is launched on the spigot principle, like a spigot mortar ; a tube slightly under 22 mm is attached to the end of a rifle barrel to serve as the spigot, and left open on the muzzle end so bullets can be fired through it.
