I really can't be arsed to go through all this again, but just because a twelve year old has produced a small line drawing on a home pc doesn't make it a viable concept.

There are many reasons why it is kak, just one of which is how to get the fecking thing rotating.
Using a bolt/spring combo with sufficient force to keep the chamber sealed until the pressure curve has reached safe levels, where does the energy to turn the bbls and operate the feed system come from ?

Besdes which, who in their right mind would want to make this ?
What use is it ? (Apart from fuelling the late night solo fumblings of adolescents.)



Canashea, one of your spotty oppos posted the same thing a few weeks back.

I must retract that statement Canashea, it wasn't one of your spotty little friends that posted the pic in the gallery.

It was you.
Or rather one of your alter egos, in this particular case Browno.

Do you really need all these log-in names ?


Talking of spotty little oiks, I carried out a quick search on the subject and apart from finding out that Canashea aka Browno aka Bashabasher has asked the same question in a number of other places including the Iran Defence forum and the appropriately named Knob Creek forum, most of the 'gen' is on paintball sites, I discovered this gem from the resident coprophiliac:

I read about the hand held minigun test by commandos, it was probably during the late 1970s, Miniguns like that in real life could also throw you up in the sky!, the recoil of it would be like a bolt action rifle firing at 6,000+RPM!!!!!!!!!!!!. I also remember when i was in the Merseyside ACF Para Cadets on annual camp in 2000, i was on the range shooting L98 rifles.
Becouse the L98 is the manually operated cadet version of the British Armys SA80, I fired the rifle , it dug my shoulder in and the handle bachsight nearly dug my eye out!, i was also complaining to the seargeants about it but they just told me to keep shooting the thing.
But if it was the SA80 or a self loading rifle, it would have been more stable.

The bolt on the minigun locks when the round is fired,like the bolt action rifle does. Blowback/Recoil/gas or self loading weapons, the bolt blows back as the round is fired so with this self powered minigun the recoil should not be so bad although the barrel may climb , also this weapon fires slightly faster than the Rheinmetall Borsig MG42/MG3 but not as fast as the proper miniguns. you never know, this weapon system could just be experimenting that miniguns could be self loading.

I also think it should replace the miniguns now becouse it is still fast firing but not too fast and does not need bulky stuff like the battery pack used to power the thing. it would also save more ammunition too.
You really are a cretin aren't you ?

Battsim, sorry I wasn't particularly clear in who my "Why?" was aimed at. Put it this way I'm with Cutaway on the "Yes, and it's bollocks." My why should be read as why......the fcuk would someone post that sh!te on here to get ripped to shreds!

I feel dirty that I could be associated with such pish!

the bolt blows back as the round is fired
Now - I'm not a weapons head but doesn't this pose a bit of a problem?

I watched Star Wars the other night and we need to get some of them Bubble throwing catapults that what disable tanks like.

Yes LB, it would be a problem - however your quote comes from the pen of that famous master guru of all things weaponry, the inimitable and execrable Browno/Bashabasher/Canashea. (note it's definitely not Ganesha.)
Only he, and possibly his mummy, knows what goes on between his ears.

Unfortunately I doubt he'll post on this thread again so he won't be able to answer your question directly.

Thats not a minigun thats fish wrappers and papier mache



Thats a gatling / minigun :D

as has been said, it is not possible to make a practical man-portable minigun, ala predator, for the following reasons:

1. Ammo usage - The Rate of fire; what several thousand rounds per min? it would not be possible for a gunner even with a number 2 to carry enough ammo to make the gun useful. lets say 3000 rds a min (probably more but for arguements sake) 3000 divided by 60 = 50 secs
so you would have 50 secs of continuous fire available. with 5.56mm calibre wpn you would have to carry 3.3 ammo boxes to get 50 secs of fire. we (most of us, except probably the ACF cadets :D ) all know how heavy 1 full ammo box is. imagine tabbing around with over 3 of them plus the weight of the gun itself & your personnal kit. If the wpns 7.62mm, it becomes even worse. I also assume that the ammo belt link would add more weight to the rounds.

2. The battery pack would weight a tone & probably be rather large.

3. Even if you overcame the above problems the torque of the spinning barrels would cause the gun to wildly slew around.

you can & the septics have mounted miniguns up to 7.62 calibre on helicopters & I think they weere trialed on ground vehicles with less success due to stability.
there is also the AC 130 spectre gunship hercules which has 2 x 20mm rotary cannon (amongst other armarments), thou these may have been reduced to one on the latest version.

not compleat, will edit later.
FOllowing on from serial 1 above...here's my two penneth...worth a view... :

you would need more than a number 2.... and the csm would be breathing out of his hoop on the replen :)

In the year 1987 the movie "Predator" (starring A. Schwarznegger) hit the screens. One of the most impressive scenes was the one where the US Commandos, attempted to fight the alien Predator. One of Commandos was armed with the distinctive weapon, a 6-barreled rotary Minigun, fed from backpack ammo box. This gave the impression that Miniguns can be used for infantry support. It must be noted, that in this movie, a special blank firing version of the Minigun was used. The electric motor was powered via a cable, hidden in the actors trousers, and the actor had to wear a bulletproof vest and protective mask to avoid injuries from the fast and violently ejecting empty cases. Had this gun being fired using real ammunition, the actor would have ended up lying on his back, being thrown off his legs by the violent recoil. The "backpack" ammo capacity, also, could be worth only several seconds of fire. lets calculate: 2 000 rounds of 5.56mm ammo will weight about 25 kg (55 lbs); 2 000 rounds of 7.62mm will weight about 2 times more, making such load almost impossible to carry on foot. |Yet this load of ammo will worth only 20 or so seconds of fire. Add some powerful batteries to power the electrical drive of about 4KWt (4+ horse-power), and the bulk of the gun itself, and you'll see that even the strongest man won't be able to carry this load, less to fire it with any chance to hit, due to extremely powerful recoil!

Yeah but no but it looks cool

Surely we could hire some local choggies to hump the kit around whilst I wander behind wearing a pith helmet and carrying a stick ?

But surely if you put a handle on it - voila - man portable!

I could fire it from the hip I could.

beerfun & Mr Bridger-well said lads. the idea is great for ally-ness in theory, but then scores -5 out of ten for practicality.
it is in fact a compleatly boll##s idea. :)

was it from a cretinous cadet again? :D

now...a blowjob operated gun....that's an entirely different proposition....hmmm.... let me see...an athletic blonde... lips that could take the pressure and make a good seal... timing would also be important... :p

what other area would me need to take into consideration...
