FD Munitions is showing off their new “caseless-in-name-only” rifle.
Currently taking on a very '80s retro-scifi vibe, FD Munitions is trying their hand at creating a platform and ammunition that is a cross between caseless and harmonica. The premise is the ammunition is caseless in that there isn’t a cartridge case that is ejected. Instead, multiple cartridges are contained in one multi-shot block that acts as a magazine. Currently, it is a five barreled design and uses five-shot blocks that can be snapped together, but there is a larger caliber in development.
Note: There are two separate “blocks,” The four-shot is a larger caliber than the five-shot.

It’s an interesting way to keep some of the benefits of caseless ammunition while dealing with the biggest failure (heat), but I’m not sure this will really ever catch on.
