HK G11 based AR

Just had another thought. You could use the heat exchanger to power all the electronics that a soldier is now expected to carry. One of the big problems is that the batteries keep going flat or unavailable. This way, all you need is a small Stirling engine and you can keep going all the way through that firefight!

Another alternative to a combination of a heatsink and recoil buffer I imagine would be like a gelatinous foam that stores inertia offering sustained fire stability as well!. Kinda like boiled egg vs. unboiled egg

Tea is more important.

Only to Poms.

Now, if had a real heat exchanger, we could use it to cool beer!

hmmm... retractable stock, diagonal quad-stack magazine, kriss-v like mechanism(except this one looks like Y), minimal length(750 mm with 21" barrel)

note: reload on top

How are you going to move the rounds from the magazine to the breech? The G-11 handled it mechanically via a clockwork mechanism, stripping each round from the block of rounds.

I'm not sure how you're going to handle the recoilling mass, either. The G-11's cycled within the butt. Having a telescoping butt precludes that possibility in yours.

Nice picture of the G-11 cutaway.

While the g-11 relied on structural inertia to dampen recoil, you can reduce felt recoil by redirecting the energy elsewhere. In this case, diagonally up and down to make it balance

the upside down triangular magazine lid loads 'em to the breech while the bottom one cocks the linear hammer.

If TDI calls theirs the Super-V. I call mine i-vY

(coz it moves like Y, it does have some v, everything is marketed with an i- prefix in the future and I'm such a cool person

)

I don't quite understand your diagram. If what your describing occurs, the entire barrel and breech recoil, while still in battery, at a diagonal, downwards along the front of the magazine? Is that correct? If it is, there doesn't appear to be enough space in the weapon's body, nor can that allow the rounds in the top of the magazine to move into the breech, as the barrel and breech return to battery. Nor do you seem to have taken into account the need to eject the spent case - unless you're going for caseless rounds?

Still using caseless rounds(sabot). Breech and barrel don't recoil; only the gas piston underneath the barrel recoils. Also, the butt stock is placed lower so that it is aligned with the barrel, ala CAR15. The telescopic mechanism is similar to HK MP5

A heat sink idea. If you can, make the frame/load structure out of aluminium, perhaps with a copper or silver conduction conduit, to carry away and provide some bulk heat sink mass. Cooling fins inside the covers will allow some air cooling, and again, some additional mass (light alloy to reduce the real weight).

Or, a different solution, can the action take being an open bolt? So no round in the chamber until the trigger is pulled.
