RIA Novosti reports:

He fired from several grenades at the house, and then started shooting at the building with the automatic rifle.

The ex-girlfriend was unharmed in the attack, but her parents were injured and later hospitalized.

Doctors said their lives are not in danger. The attacker was arrested by police.

Crazy.

About 6 months ago Metal Storm was awarded AU$1.4 million in development contracts from the US Navy to develop a 12 guage (.729″ caliber, not the 12 gauge shotgun cartridge) multishot weapon that mounts under an M16 and M4.

The MAUL has no moving parts and weights just 2.75 pounds.

All four rounds can be loaded into the chamber at once and are electronically ignited. It can fire lethal rounds, such as grenades, and non lethal rounds.

The weapon system was exhibited at AUSA Expo this year and should be in production next year.

The RPG-40 was on display at MSPO 2008. The Centre for Research and Development Equipment Mechanics (OBR SM) and Military Technical Academy, which I assume are Polish organizations, have developed the RPG-40. Despite its name it has nothing to do with the Russian RPG-* arms and does not fire rocket propelled grenades, just the standard 40mm variety.

It holds 6 rounds and features an oversized chamber so a variety of lethal and non-lethal ammunition can be chambered - limited by how much pressure the weapon can withstand.

It may be in direct competition with the South African Milkor MGL (M32) that is currently used by the Marines in Iraq. It looks like it has a very similar spring-loaded magazine, which rotates after a shot has fired. I would not be surprised if the MGL technology has been licensed.

I have done my best to find accurate information about this firearm on the Polish MSPO 2008 website. I do not speak or read Polish so I had to rely on Google Translate. If I got something wrong, please correct me in the comments.
