Slightly modified doohickey

Although I'm a big fan of a good old fashioned killdozer.

Yes that's a TE3 with rubber tires. I will not be taking questions

XF-85 Goblin

Rocket wrench.

Scorpion rocket launcher. (This one is legitimately neat. YES, the designers know what backblast is, and the design redirects it to the side and away from the shooter. NO, the launcher is not permanently attached to the M16, it fixes using the bayonet lug and goes on and off just as quickly.)

Praying Mantis.

Not sure if this counts, but I feel like I'd be put on a list for watching this

RAW

Gallipoli "drip rifle".

RPG-76.

Idk i made this a while ago from parts I had laying around in my room. Let's say I'm terrified when I use it...

This machine kills fascists.

I had no idea the Shinzo Abe thing was a doohickey. I take it that's not a regular bullet? How did it work?

Crowd control M113.

imagine being killed by a doohickey

the twi-

Do the Shuttle Carrier Aircraft count? The space shuttle is an aircraft with the flight characteristics of a svelte brick. It'll land just fine. It only lifted off in Cowboy Bebop. So to fly it from place to place, without taking the long way up, it'd piggy-back atop secondhand 747s. They didn't bother replacing the American Airlines livery for at least five years.

The mounts on top read "attach orbiter here - black side down."

Make Gauss proud

I made in my teens a gun from Lego Technic that shot a lady cracker with another lady cracker. It got about 20 m before the cracker exploded after 0.5 seconds.

Sadly no foto, and it got unusable after about 20 shots.

Good ol' rocket pod technical

Toob

M142 kit.
