Link to the adjustable rocket valves. I can guarantee these fit in all AR15 variants, G3s and FAL from VFC. They probably fit nearly all VFC GBBRs to be honest, check on the heavy recoil discord if you’re unsure:

So what is this screw at 5:45? I screw it all the way not knowing what it is, and now some stuff sticks out inside the nozzle. What am i supposed to do and what does this thing even do

Maintains the seal, if you tie it all the way it can break the seal
