I'm at a loss here.
I'm not a gunsmith, but how about a super light spring to make it cycle like a direct blowback?Bull
I am with you! He had to improvise somethin on the Gas Block. I also can not understand how it is cycling! Because obviously it is a Gas Impingement system.
It has me baffled!
Impractical to say the least. Hell- I can’t imagine there even being enough barrel to get any rifling in that thingPrimer
I have reviewed the Video again and again. And I think you have something there! I would say he has made a special Lighter Buffer, Modified the Spring and may have modified the Bolt? I also noticed an off set in the Low Profile Gas Block on the Rifle. If the Spring, Buffer were modified all the Gas would have to do was unlock the Bolt Lugs from the Barrel Extension Locking Lugs when the round went off. And with a modified system it could almost act like a blow back system at that point to cycle.
The reason I think your onto something, is by closely viewing the location of the Ejection Pattern when the Casings are Ejected.
Here is a chart to confirm he has obviously modified the Gas System. You will notice compared to the Chart that the Casings are almost flying back at 5:00 O'clock in the Yellow Section of the Chart. That is not normal at all for the AR-15. IMO he had to modify the system because if he had not the Rifle would not function. With every part being noral it would be short stroking and not running like it is.

So other than it being a stupid Idea and totally impractical. To each his own!
