Oddly enough your right! But if you click on the home icon, then guns and scroll down past the AK and some papers of interest, there it is! About 25-30 down the list. Funny cuz it is the same URL...?

Fella's;

If I remember correctly, wasn't one used in a spy movie of the era?  Possibly a Bond movie but I certainly wouldn't swear to it.  As I remember, the accuracy was about that of a young boy pissin' into a high wind.

the actual pistol was a real poor manufacture, all pressed parts.  the idea was a throw away gun and self disposable ammo.  Saw the gun one time in Philadelphis; probably the only gun I didn't have any desire to own!

 

IIRC the Am. Rifleman had a review...poor....but the wave of the future.  Designed by Buck Rogers.

JSG   I can't get into that site.  lost my 'puter for an hour as it crashed at that link.  So post hear what it sells for.  thanks

Just click on the "guns" Icon
then scroll down about 25-30 items, but I'll watch it for you.

Gotta say it was a neat idea, just poorly executed.

It appears that MBA also made some slightly better models, they never sold either.

If you have ever seen an unguided missile launch, you would never consider such and absurd device.

sites   or sights??????

once the missle leaves its launch pad, GyroJet is on its own...no brain, no course corrections...just mindless drift all over the countryside.

Fella's;

Looked it up, it was used in the Bond movie "You Only Live Twice".  It's there if you want to see it in action.

IIRC Popular Science did an article on them and had a
picture of one being fired showing the projectile path in
a swimming pool.

Be careful what you decide to not like. Your wife may wear one. Your son may ride one. Your daughter may bring one home. You may have to have one someday.

A water test? Bullets do weird things in water. Don't our Candoodlian brothers have a tournie in the fall, whereas a target is shot over water and the bullet has to ricochet off the lake before hitting the target?

Seen softpoints do all kinds of wierd zigs and zags when fired into ponds, doubtful the missile bullets would fair a whole lot better.

Bear, IIRC it was sort of a corkscrew trajectory with
lots
of bubbles depicting the path. zounds...that was more
than 45 years ago so give me some slack with my memory on
something I haven't recalled since then. Hmmmmmm...wern't
the rocket ports angled to impart rotation to the
projectile?

Did some digging:

http://en.wikipedia.org/wiki/Gyrojet

Accuracy is increased by spinning the projectile. This is
achieved for a bullet by being forced against spiral
rifling grooves in the barrel. A rocket does not have
enough initial energy to allow stabilization this way.
Spin stabilization of the Gyrojet was provided by angling
the four tiny rocket ports rather than by forcing the
projectile through a rifled barrel.

However in later tests accuracy was very poor; the
difference seems to have been due to a manufacturing flaw
in later production runs which partially blocked one of
the exhaust ports, creating asymmetrical thrust that
caused the projectile to corkscrew through the air.[13]

If you look at all the Billion of dollars spent on jet/rocket weapons by the military.  Germans/Americans/Russians have never made a rocket/jet that had even poor accuracy without some feedback guidance system.

The bazooka was the best attempt, but  IIRC the propellant burned out directly at the front of the muzzle, so it really wasn't a sustained rocket per se.

Someplace in the system you need a gyroscope.

One more thing about this gun, if the muzzle was less than 10 feet from an intended target, it would bounce off. It took some distance for the rocket to get enough velocity to penetrate.......................Kingpin

Gyro jet update to 2014.

GOOGLE "smart bullet". Its got the stabilization thing all
figured out.

There may be several species on them. I didn't get into
the subject too deep.

All interesting, but the Barret bullet (5,788,178) has no new technology.  It is just old missle guidance stuff but said to be put in a bullet.  Even using MEMS technology no one has done it in a shoulder based rifle cartridge.  there just isn't sufficient physical space  to make a firable projectile and have mechanical response time to maintain control.

 

Interesting, but best in the context of Pinewood Studio, "Bond--James Bond"
