A drum type ammunition storage system has an outer, stationary drum with two, interlayered, helical partitions; and a rotating core with a plurality of longitudinally extending guides, to provide two helical trains of rounds, each having a first rotational velocity, which are merged to provide a single train having a second rotational velocity which is twice said first rotational velocity. The helical partitions are at a longitudinal angle to the longitudinal axis, to support the rounds at an angle to the longitudinal axis.

Might just want to wait and see how Nerf does it.



Here's the press release from the New York Toy Fair 2008.

Quote :
"NERF N-STRIKE VULCAN EBF-25

The top-of-the-line blaster for mission supremacy, the NERF N-STRIKE VULCAN EBF-25 blaster is a 25-dart belt-fed fully automatic blaster that will intimidate any opponent. This impressive blaster comes complete with a fold-up tripod to steady your aim, 25 sonic micro darts that whistle through the air when launched and a 25-dart belt.

they work not much differently from a regular magazine, except they do it in a circle instead of a straight line

except for ammo drums on a belt fed weapon, which are basically just a big box to hold the belt.

Yeah, it looks quite a bit like the M-249 SAW. I'm interested in knowing if you can string several belts together. Looks like the feeder box may only be able to hold 1 belt.

Toys have come such a long way since the early 80's. It's quite amazing.

i don't know how the belts on the toy work, but i would imagine you could string belts together.

on a real belt fed weapon, you can string as many belts as you want together very easily, or break them up into smaller segments.

ok, step 2

find a big spirally spring that won't squish foam darts

the nature of the foam darts might be a limiting factor

mount each dart inside a hollow copper casing or something? you'd need darts smaller than the chamber of the gun though >.> or do like guns always have and use a standard mechanical clip
