Where did you get these numbers?

From Paul Whitney at Escort Japan, who works along with Shoei, TOP, and Sun Project making GBB engines for their guns. I trust his knowledge on the subject matter. Escort engines are known for being remarkably gas efficient.

Well... yea thats quite a reliable source Id assume. Unless they are afraid of the competition

I bet that by the time these GBBs are out, they will be much more gas efficient. I mean, the recoil is much less than on the escort, I'm doubting those numbers still...

Time will tell...

I still want one.

Oh so do I. I've dreamt about internal-gas GBB rifles (and ESPECIALLY an AKS74U) since I got into this sport. However I'm skeptical that the TK will end up being any sort of commercial success simply because it'll be way too damn expensive. That looks like a VFC or Inokatsu kit he's using which is easily CAD$1,000 right off the bat. Add his custom gas internals for, say CAD$500 (an Escort M60 engine is $850), then a rough estimate of $200 per magazine? Just not a practical skirmish weapon at that point.

I think one issue with the efficiency stems from the fact that TK will have to be using direct unregulated gas pressure. External rigs benefit from a regulator that will allow you to tune your output and achieve a much more consistent and efficient flow.

liquid charge magazine blow back

Yep, it's in the mag.

great summary by ancorp and gryphon.

I'm just wondering if these would be mass production, or limited production.
