I didn't think the HW80 could be gas-rammed...well not without some major re- engineering, due to the factory piston having a central rod as the mechanism to latch onto the sear.
That's why the HW90 (gas-rammed) doesn't have the Rekord trigger.
Any way, I stray from the topic.
It would make things very interesting but you'd have to be supremely confident over their quality control before you bought one.
