The EMG-01B is a small portable rail gun made by Arcflash Labs. Introduced in 2017, it can throw magnetic dowel pins approximately 1/4″ x 3/4″ (6mm x 19mm) at about 150 fps (45m/s). It does this with a series of 8 capacitors and electromagnetic coils, and holds 18 projectiles in its magazines. Generating just under 5J of energy per shot, the EMG-01 is similar to a BB gun, and it was this lack of power that led to development of the GR-1 Anvil.

Shooting an Original Hotchkiss Revolving Cannon
Several years ago, my friend Joe Lozen had an opportunity to fire an original Hotchkiss Revolving Cannon. He kindly sent me this clip – it is the only footage of one of these actually firing […]

White-Merrill Experimental Model 1911 Pistol at James D Julia
In the aftermath of their rejection in the US 1907 pistol trials, Joseph White and Samuel Merrill continued working on handgun designs. In 1911, Merrill wrote to the Ordnance Department to inquire about whether they […]

Taurus Curve: My Worst Backup Gun Match Yet!
A little while back during the summer I went to our monthly Backup Gun Match with, of all things, a Taurus Curve. Why do I even own one of those? Well, I found one new […]
“Kid, you’ll shoot your eye out!”
Jokes aside, just what was this gun supposed to do? Shoot bullseyes at a target competition?
I am under the impression that it was probably more as a proof-of-concept project than anything practical.
One of the designers, in the previous video for Arcflash, said that projectile speed relates to the capacity of the capacitors, and capacitor capacity is steadily increasing over time.
So you make this weapon now, and it’s 45m/second, and then you wait one year and use the capacitors which have then become available, and it’s then firing say 10% faster, and so on.
I have no idea what the rate of improvement is, or the rate of significant breakthroughs.
“(…)what was this gun supposed to do?(…)”
To be curiosity I suppose.
“(…)target competition?”
Now I am wondering about muzzle velocity consistency. It muzzle velocity spread lesser or greater than in comparable fire-arms?
And still considered a firearm in the PDR of NJ (no, not joking)
“(…)PDR of NJ(…)”
What is this?
He just said, “People’s Democratic Republic of New Jersey.” It’s an insult aimed at New Jersey’s gun laws, which are so strict that school children could be incarcerated WITHOUT TRIAL as terrorists for mere possession of a lone gun barrel (without receiver or stock attached). I could be wrong, of course.
Well I know that slingshots are banned in that state. What if the child got caught with a wrist rocket. Wonder what the charges would be?
“Conspiracy to commit acts of terror” or “attempted assassination” are the things I imagine in the papers.
interesting and futuristic weapon
What is the weight of that projectile?
We can approximate “(…)magnetic dowel pins approximately 1/4″ x 3/4″ (6mm x 19mm)(…)” using steel (which density is ~ 7,7 g/cm³) cylinder with diameter 0,3 cm and length 1,9 cm. This gives volume ~ 0.5372 cm³ and therefore mass ~ 4.1365 g.
