typical german overengineering
(sh.itjust.works)
Context? Seems a cool one
It's the HK G11 and FN P90. Both guns have a magazine where the cartridges aren't in line with the chamber so each cartridge needs to be rotated before it can chambered. HK decided to commune with ancient clockwork gods to learn the secrets of kraut space magic while FN just went with a curved ramp.
As far as I know, the only thing that keeps the cartridges moving down the slide in the P90 is the magazine's spring pressure. Are they more likely to jam compared to conventional receivers?
edit: but then, with so few moving parts, a confident smack might unclog the slide. I don't know, I'm European.
For the last few rounds, there are IIRC three tethered dummy cartridges that are pushed by the spring into the slide, so that the last few rounds are properly fed and can't rattle around.
Cartridges aren't gravity fed through the slide or anything. They are pushed through and into the receiver by the pressure of spring, same as any other gun.
My thoughts exactly.
First solution might look over engineered (in not qualified to decide as I'm german) but probably works in a lot of conditions (running, jumping, sudden movements, shaking, like a gun may experience during use in conflicts) whereas the slide maybe only works when the sun is shining, the birds are singing and the people are picnicking or such.
The slide works in all conditions afaik. It's not gravity fed or something. It's full of cartridges under presure from the spring, same as any other gun, and rounds are pushed into the receiver one by one. IIRC three dummy rounds are tethered to the end of the spring, which allows the spring to push the last few cartridges into the slide and out of the magazine.
FN P90's magazine turns the bullets 90 degrees by turning them with its feed geometry. It kinda looks like a slide for bullets if you squint hard enough. HK G11 uses about as many parts as in an average Swiss watch to do the same thing.
I wonder if the G11's mechanism is so overengineered because it uses caseless cartridges.

A community for your defence shitposting needs
Rules
1. Be nice
Do not make personal attacks against each other, call for violence against anyone, or intentionally antagonize people in the comment sections.
2. Explain incorrect defense articles and takes
If you want to post a non-credible take, it must be from a "credible" source (news article, politician, or military leader) and must have a comment laying out exactly why it's non-credible. Low-hanging fruit such as random Twitter and YouTube comments belong in the Matrix chat.
3. Content must be relevant
Posts must be about military hardware or international security/defense. This is not the page to fawn over Youtube personalities, simp over political leaders, or discuss other areas of international policy.
4. No racism / hatespeech
No slurs. No advocating for the killing of people or insulting them based on physical, religious, or ideological traits.
5. No politics
We don't care if you're Republican, Democrat, Socialist, Stalinist, Baathist, or some other hot mess. Leave it at the door. This applies to comments as well.
6. No seriousposting
We don't want your uncut war footage, fundraisers, credible news articles, or other such things. The world is already serious enough as it is.
7. No classified material
Classified ‘western’ information is off limits regardless of how "open source" and "easy to find" it is.
8. Source artwork
If you use somebody's art in your post or as your post, the OP must provide a direct link to the art's source in the comment section, or a good reason why this was not possible (such as the artist deleting their account). The source should be a place that the artist themselves uploaded the art. A booru is not a source. A watermark is not a source.
9. No low-effort posts
No egregiously low effort posts. E.g. screenshots, recent reposts, simple reaction & template memes, and images with the punchline in the title. Put these in weekly Matrix chat instead.
10. Don't get us banned
No brigading or harassing other communities. Do not post memes with a "haha people that I hate died… haha" punchline or violating the sh.itjust.works rules (below). This includes content illegal in Canada.
11. No misinformation
NCD exists to make fun of misinformation, not to spread it. Make outlandish claims, but if your take doesn’t show signs of satire or exaggeration it will be removed. Misleading content may result in a ban. Regardless of source, don’t post obvious propaganda or fake news. Double-check facts and don't be an idiot.
