The problem with a gas gun when you use a really high efficiency suppressor (smallest bore for caliber and good baffle arrays) is that you get a lot of back pressure in the system, which vents out the chamber.
On the AR15, it also manifests as gas vent relief hole pop in the BCG through the ejection port, so this is why I prefer .30 can cans with 6.5mm, to allow more relief out the front.
Will be interested to see the new TBAC cans.
