It was developed as one of many proposed weapons to fill the U.S. Army’s desire for a squad level weapon that could be fired from inside a building, and packed more anti-armor punch than a 40mm.

Think about the time period and planners thinking about how to stop hypothetical hoards of BMPs rolling through West Germany.

This, along with other weapons, weren’t adopted because the Army pivoted doctrine away from focusing on new squad level weapons that could damage IFVs, to larger weapons like the TOW that could take out MBTs. The change in thinking traded lightweight and abundance organically to infantry on the move for better performance.

I was gonna point out that printed guns usually use proper metal barrels, but no, that fuckin thing sitting in the ejection port looks like a printed barrel. What the hell.

You mean the cool kids list? 😎

The favorite practice weapon of the gravy seals

Yes, indeed it is

100%

It does look very familiar

a killamajig.

Nice word you have there. Would be a shame if someone stole it

sounds like something a gobbo would say. love it!

“Rifleman’s Assault Weapon”.

Documentation is pretty spotty. The publicly available stuff tends to be corporate marketing material which is written by people who might not fully understand the technical aspects and/or are fudging or intentionally simplifying.

The overview is that it’s a rifle launched multi-mode munition for the M16.

“What does it do?”

“You’re looking at it.”

My guess is that they can kind of steer it by driving only the right or left side wheels. It’s diesel electric so they could individually control each wheel motor.

So this is where Bungie gets their exotic weapon designs from for Destiny

Looks like a lego guy at first.

The significant plumes of smoke generated when the weapon was fired indicate that it does not make use of commercial small arms ammunition propellant (‘smokeless powder’), and may instead use blackpowder or an alternative propellant. This makes the use of ‘separate-loading’ ammunition (i.e., propellant and projectile loaded separately into the weapon) more likely, as well as increasing the likelihood that the weapon was a muzzle-loading design—that is, loaded from the bore (‘front’ of the barrel), rather than the breech (‘rear’ of the barrel) of the firearm.

the weapon appears to use an electric firing mechanism. Images of the firearm show that an electrical wire passes through each endcap. …This high voltage creates a hot plasma arc between two conductive contacts that can be used to ignite flammable materials

Probably the most prominent electric firing mechanism for 3D-printed firearms has been developed by the user ‘@SuckBoyTony1’. This mechanism uses an 80 kV High Voltage Pulse Generator that converts 6–12 V (the electric potential typically provided by battery packs such as that seen with the assailant’s weapon) into 80 kV. This high voltage creates a hot plasma arc between two conductive contacts that can be used to ignite flammable materials

What’s with this level of overengineering? Just get the Piezo from a lighter and maybe that igniter powder from fireworks and good.

Looks pretty rad to me

Quite hardcore

You might even say it’s the core of demon…onic s-stuff

fuck

It’s the demon core.

TLDR: there was an “experiment” that involved using a screwdriver to hold the top half of the cover to get the core as close to critical as possible. One time the screwdriver slipped and the top fell releasing a huge amount of radiation in a very short amount of time.

No explosion, just radiation and heat. Everyone nearby is dead, just not instantly.
