As the resident engineer, I'm curious to see what your take is on this. Do you see any real advantages to this operating principle? Looks pretty weird to me, but interesting.

i saw this being used on future weapons,, very clever
probably not as easy to fix if it went wrong

It will be intresting to see independant test results [if they haven't arady been done]. I'll only put so much value on 'test results' reached by the company itself, and I'm speculative about taking their word on everything when just a few paragraphs below talks about personal sales and possible enterprise partnerships. Seems more of an advertisement picking and chosing figures they see fit for a good ad. But I could be wrong. As for the concept behind the system itself, t seems logical enough to work, but then I'm not the resident engineer Herald is I just lke playing with guns ]

Most of what they are doing is based on using a rocking chair countermass and its pendulum  motion cycle  to coincide with the maximum recoil from the powder discharge. Some of the gas discharge is redirected to slam that countermass forward into the recoil vector line. Its ingenious I must say. But unless I got my hands on it and tore it apart, I'm dubious about its claims as to ease of cleaning [the gas tube must be a nightmare.]. I'm also not wild about the way the demonstration weapon is laid out. We are built like men, not like short armed chimpanzees if you know what I mean?

I can also see a means using their principle now for doing what they try to do; that is laid out much differently-possibly better..I need to think about it.

Seems kind of like a solution looking for a problem, or at least it's not really in step with the general trend away from automatic fire these days.
 
I suppose if the weapon had a mechanism that significantly increased controllability in automatic fire, though, it might prompt some changes in thinking/doctrine.

  I agree withe Herald, would really have to get my hands on it first. I am not a mechanical engineer but would like to at least see how it is for ease of assembly/disassembly, how many small parts if any when field stripped etc. just to see if the KRISS followed the K.I.S.S. principle. 
 
 Also the chick in the video (Paula?) appears to have a nice rack.

There is something to be said for designing a weapon that would mitigate muzzle rise even in single shot. My thinking is that a recoil powered countermass that cycles in line with the recoil force vector  like a spring oscillator instead of a  pendulum oscillator would make for a mechanically simpler and ergonomically friendlier weapon. Assuming you could make it a spring mass you could even get rid of that crazy gas tube geometry involved in tapping the gas from the KVSS system and make it a pure mechanical oscillator. Everything is inline, stacked  held together with pins and threaded cap screws and when parts wear out,  you just take the old stack apart and replace it with factory  new. The first echelon user should be able to do it. I can almost see it.......

you could have an smg in .50ActionExpress
could it be used to tame the recoil of 7.62nato?

   I can watch their video without having to buy one.  Now if she came with the gun they might have a sale dependign on what their return policy was.

One thing I can see immediately that they did is place the barrel lower in relation to the hand so the recoil force works on a smaller lever, the wrist being the rotation point of the lever. They've use that principle in one of their earlier designs. Is the correct term low bore line for this?

I haven't completely figured out the moving weight.
- The mechanism pushes a weight down, which would push the gun up.
