Rearward thrust goes into the recesses on the barrel extension, which are perpendicular to the direction of thrust. The cam in the bolt carrier doesn't start unlocking the bolt until the bolt carrier has been moved a good deal rearwards. Off the top of my head, I'm pretty sure the firing pin on an AR-pattern rifle can't even protrude through the bolt face unless the locking lugs are fully engaged.
If you're going through hell, keep going.
In terms of charging handles, have you considered something akin to the Lee-Enfield in relative position to the trigger?
Maybe a "Mad Minute" edition?

I would like to see a rendering and would also like to know the weight of an actual build. Will it actually be light or would it be the same weight as a comparable AR15/AR10?
Can't wait to see a finished product... definitely interested.
Will buy it for sure. Want it for eventually convert my AR10 if sh it hit the fan..
This feels like giving up.....
I can't wait to start a build on this platform. I like contingency plans.
