Title: Drum to Cylinder conversion?
Post by: valavaern on <01-30-13/2216:20>
Not sure whether this really belongs here, or in the rules section, but... what's the general opinion on being able to mod a drum-fed gun to use a cylinder.  I'm specifically thinking of shotguns and grenade launchers, so that they can take advantage of ammo skipping's full functionality.

I suppose you could use the mod for converting a gun to a drum magazine on the weapon but just change the drum for Cylinder. I can't seam to think of anything more clever than that...

Yeah, it's basically gonna be the same level of physical change as the drum mod is - though you would become eligible for the Increase Cylinder mod.

That said, it seems to me that you may as well just go with the Additional Clip mod to add a second internal magazine, and the Ammo Skip System with one additional slot to represent being able to grab from any point in the mag.

In either case, I think you're looking at a change to Concealability (still something of a factor for shotguns), as well as either level 1 or level 2 Custom Look being applied - though likely without needing slots, as the benefit is coming from the appearance shift cause by the above mods.

Are you proposing something like the Pancor Jackhammer?

Can't say that that's ringing any bells, actually.

Oh okay, it was  Bullpup gas operated shotgun with two cylinders stacked inside the magazine, which could switch from one to the other, though I don't know how the action would work.

The Pancor Jackhammer has probably appeared in more video games than actual models were made.  ;D

As in actual, rotating revolver cylinders?  Because I was proposing something a little more elegant.

If I remember correctly there were 6 Pancors made. Here's the design schematic for it (http://en.wikipedia.org/wiki/File:Jackhammer_blow.jpg), it would appear to be a gas operated bullpup autorevolver, how do you like that?

I'm kind of amused that that exists.

Me, I was thinking parallel internal magazines, with the loading mechanism being able to grab a slug from anywhere in the magazine - every spot where it could rest has the mechanism for inserting it into the chamber.  This would probably involve building a little more stuff onto the weapon, hence the point about custom look.

Would it work by having a really long bolt draw? And an open round in the forward cassette to push the ammo in the rear cassette through? Or, how would it work?

In addition, its going to lose some weight, so recoil may become a bit more of a factor (or would it be less of a factor, I forget its late).

I'd have to sit down and start sketching to really think it through.  That, and I'm not THAT familiar with firearms design.  Depends a little bit on how the original magazine is in the weapon, however.  Basically, you shove the original magazine over, put the other one in beside and parallel to it (presumably on the opposite side of the chamber), take the mechanism by which the magazine loads the round into the chamber and expand it such that the magazine can eject any single slug into the loading mechanism which then brings it into the chamber.  This is, of course, a smartgun as the Ammo Skip System requires that.

It just needs an underbarrel shotgun now, and an integrated comlink and melee hardening.

...  A shotgun with an underbarrel shotgun?  In any case, I figure it's already about 4 slots in, can't do all that much more to it - and still need recoil compensation.  Sling+Foregrip might be a good idea.

I guess if you wanted to do it the easy way then. Yeah, or electronic firing, if that can be added to SGs, oh wait... that's 2 slots, yeah, Sling, stock and shock pad, and a forgrip.

If you have a drum mag you already have a circular thing, so you can use that as the basis for an oversized cylinder.  You will probably loose some ammo capacity for the extra parts you need to install, but putting a cylinder mag inside a drum should be possible I think.

You've never seen an over-and-under before?

I was actually proposing a drum (Clockspring) Magazine grenade launcher with an underbarrel masterkey, but yo dawg.
we heard you liked pump actions,
so we put a pump action on your pump action,
so you can shoot while you shoot.

Depends on how the drum actually feeds into the weapon. If the bolt actually passes through a slot in the drum to chamber each round, then yes, the conversion to a revolver feed will be somewhat less complicated. It'll still be a lot of work.

However, if it's like most drum mags, the ammo feeds out of the drum into an extension piece, which means the chambering mechanism for those weapons are more or less the same type as you see that use standard stick magazines.

Heck, many real life drums can fit into standard magazine wells without modifying the weapon at all. Witness the Beta-C style drum mags that fit in many assault rifles (https://www.google.com/search?tbm=isch&q=beta-c). Or 50-100 round drums that can feed into pistols.
