I Accidentally Blew Up My Gyrojet


Never expected to see this. I have seen these things being fired in a documentary. But I think the footage was in black and white and blurry.

The final malfunction with the barrel flying out is downright cartoonish. The rest of the footage is quite cinematic. Maybe this will spark interest in building new rocket pistols? But I doubt it.

If I recall correctly, they would work completely under water.

It would be interesting to see that, too!

Gyrojet pistols actually saw some combat service with MACV SOG operators in Vietnam (SOG having purchased the pistols under the mistaken impression they were silent), including being used by First Lieutenant George Kenton Sisler, SOG's first Medal of Honor recipient.

Neat. I think I recall reading about these a long time ago, in a book.

One of the headshots sounded like a ricochet but it had more of a whistle to it.

That's mentioned at the end of the video. In Herreras head-canon he was carrying it when he did the stuff that got him that Medal of Honor.

No slow mo shot of the good dome shot.  

Otherwise, it was a very cool video.

I fell in love with the Gyrojet after reading Niven's "The Meddler", when hard boiled detective Bruce Cheeseborough carried one.

These are awesome, especially in slo-mo.  My dad says he's remembers seeing them advertised in the 60's/70's.  It's too bad the ammo is all so old, that seems to be the main problem with their reliability.

They also seem super dangerous, since it's self propelled a ricochet that changes the bullet's original trajectory could send it full speed in unexpected directions.

The problem with rocket guns is, besides accuracy issues, the projectile is moving slow up-close.

They found several of the projectiles on the berm.  They didn't appear to be prone to richet.

Loved seeing the slo mo of it.  Somebody needs to 3d print new rounds for it.

With a name like "Cheseborough" you've got to be tough.

I watched that video earlier. Very cool gun.

$150-200/shot though.

I wonder why no manufacturers have continued to develop it! That pistol looks rather crude. Version 1. I bet someone in the Military has messed around with that idea.

I knew a guy that had some Gyrojet rounds/cartridges. I always thought it was a neat idea.

IIRC the fuel burns out with a short distance of the muzzle and it’s ballistic from there.

Something like that scaled up would make for a cool machine cannon or tank gun.

They found 3 - including the one stuck in the barrel.  A couple of times out of the gel targets the rocket had clearly deviated from its original path and looked to be heading in a different direction.  At one point they allude to a projectile that clearly went over the berm.

One of the rounds that hit the berm you can see skittering around still under power.

I’d be hesitant to shoot them. Especially at gel. If that thing had flipped back around it still had plenty of propulsion left.

Didn't McUzi have one of those things?

BTW, Demolition Ranch did an episode with the Gyrojet, too.

Glad someone got the footage before they are essentially all expended or expired.

Not what is seen in the video.

It's worth watching.

Not rifled and small bore... so... not a firearm and not a DD?

Also meaning, you could make a 100% legal full auto gyrojet.

Mk 1s, as in the video, were 13mm so were DDs, think they're all C&R now.  Gyrojet switched to 12mm rockets after the 68 GCA Infringement.

Still classified as a firearm since it uses burning propellant to propel a projectile. No rifling allows you to avoid AOW and SBR but full auto still applies

You could do a similar one with compressed gas that could be full auto as its then an air gun.

The rocket pistol sucked in Resident Evil 8.

I just read about him and his MOH citation.

Thanks for posting his info.

That was possibly the best Brandon Herrera video and an excellent collaboration.
