The discussion of the Alien series of films and the props used in them is the aim, but if it's got Big Bugs and Big Guns, then they are welcome too!

It would still need a bolt and open ejection port to clear a jam, or dead round. Or, it would somehow need something that could do the same thing with an ammunition related malfunction.

The pulse rifle does have a selector switch at least.


No it wouldn't. The bolt is for inserting, and extracting the round/casing into the fireing position. If the ammo is placed into the fireing position, by the magazine (ie just lifted by the mag spring right into position,) there is no need for said bolt. Also there would be no fireing pin, as it would be electricly fired. As for clearing a jam, acording to the HK G11 website (a real Caseless weapon), it doesn't jam. Although that particular weapon does have a bolt, but only because the ammo isn't placed into the fireing position, unlike the PR should be.

As for a dead round would that even be possible in a caseless weapon? The entire back part of the ammo is propellant so any part of it ignighted would fire the round. So the only way for it to be dead is if the propellant was damaged, in which case you would notice when you reloaded it into the mag, or it would be damaged in the mag itself, in which case you would also see the damage to the mag and not in load it in the first place.



Just thinking, on the G11 the 'bolt' is a rotating assembly designed (among other things) to seperate the round being fired from the other rounds to prevent mass detonation of the magazine...

Surely the M41-A would have to have a similar 'bolt' to prevent the same problem occurring?

Any weapon can jam. I have seen it with the "un-jammable, perfect" weapons like Glocks and the vaunted Ak47. You need a way of manually clearing a bad round from the weapon. Each round also needs to be kept separate from the rest in the magazine to prevent accidental detonation.

I'm just coming from my real world firearms experience on the matter, so your mileage may vary considerably.

1) Caseless ammo is an explosive, and explosives can fail to go off. The real world caseless ammo for the G11 was sensitive. I am assuming in the future, it would be far more robust and efficient, making most of the "round" the projectile.

2) There would need to be a bolt/device to eject a live round to unload the weapon for cleaning and/or inspection, and a way to quickly eject a bad round in combat.

3) There would need to be a bolt to separate the magazine supply of ammo from the round to be fired to prevent a chain explosion. Also, the round would need to be seated in the barrel so the pressure of detonation would not destroy the weapon, and/or blow the magazine out of the magazine well. The bolt would still be a necessary component.

4) A counter is just fluff, and not really needed. Handy, but not necessary.

Like I say, your mileage may vary ...
